Data Set Overview:The Mars Express (MEX) Planetary Fourier Spectrometer (PFS) DataArchive is a collection of raw data collected during the MEX Missionto Mars. For more information on the investigations proposed see thePFS documentations in the DOCUMENT/ folder.This data set was collected during the MEX Mission phases:- Sixth Extension Mission PhaseMission Phase Definition:It should be noted that the Mars Express (MEX) Planetary FourierSpectrometer (PFS) group uses mission phases which deviate from theones defined in the MISSION.CAT files given by ESA in order to keep thekeywords and abbreviations consistent for Mars Express, Venus Expressand Rosetta.Those mission phase abbreviations are also used in the data descriptionfield of the dataset_id.MaRS mission name | abbreviation | time span:Near Earth Verification | NEV | 2003-06-02 - 2003-07-31----------------------------------------------------------------Interplanetary Cruise | IC | 2003-08-01 - 2003-12-25----------------------------------------------------------------Nominal Mission | Nominal | 2003-12-26 - 2005-11-30----------------------------------------------------------------First Extension Mission | EXT1 | 2006-01-01 - 2007-09-30----------------------------------------------------------------Second Extension Mission| EXT2 | 2007-10-01 - 2009-12-31----------------------------------------------------------------Third Extension Mission | EXT3 | 2010-01-01 - 2012-12-31----------------------------------------------------------------Fourth Extension Mission| EXT4 | 2013-01-01 - 2014-12-31----------------------------------------------------------------Fifth Extension Mission | EXT5 | 2015-01-01 - 2016-12-31----------------------------------------------------------------Sixth Extension Mission | EXT6 | 2017-01-01 - 2018-12-31---------------------------------------------------------------- Data files ---------- Data files are: The tracking files from Deep Space Network (DSN) and from the Intermediate Frequency Modulation System (IFMS) used by the ESA ground station New Norcia. Level 1b data are archived. The Geometry files All Level binary data files will have the file name extension eee : .DAT Data levels ---------- It should be noted that these data levels which are also used in the file names and data directories are PSA data levels whereas in the PDS label files CODMAC levels are used. PSA data level | CODMAC level ----------------------------- 1a | 1 1b | 2 2 | 3Data Set Identifier-------------------The 'DATA_SET_ID' is a unique alphanumeric identifier for thedata sets. The PFS data set ID is generated using the follow syntax:---- ---V Acronym | Description--------------------------------------------------- | MEX this is fixed, and is the mission ID for | Mars Express.--------------------------------------------------------------------- | M this is fixed, and refers to the target of Mars--------------------------------------------------------------------- | PFS this is fixed and identifies the instrument | as PFS (Planetary Fourier Spectrometer)---------------------------------------------------------------------| 2 this number indicates the level of processing | the data has undergone on the CODMAC scale--------------------------------------------------------------------- | EDR this represents the type of data in the data | set. For the standard PFS deliveries, this will | always be set to 'EDR' meaning 'Experimental Data | Record'--------------------------------------------------------------------- | this is a descriptive section of the ID and will | typically refer to the mission phase ID or an | orbital range for the nominal mission. Values are: | | NOMINAL nominal mission phase. | EXT1 first extended mission phase. | EXT2 second extended mission phase. | EXT3 third extended mission phase. | EXT4 fourth extended mission phase. | EXT5 fifth extended mission phase. | EXT6 sixth extended mission phase.--------------------------------------------------------------------- | <1.0> this is the version of the data set, | starting at 1.0 and increasing incrementally if | changes are made to the products or the dataset | itself.---------------------------------------------------------------------When all of this is put together, it provides a data set ID of theformMEX-M-PFS-2-EDR-NOMINAL-V1.0orMEX-M-PFS-2-EDR- EXT1-V1.0 VOLUME ------The VOLUME_SET_ID follows a strict formation rule defined in [1],section 19.5.1, with theCountry > IT for ItalyGovernment Branch > CNRDiscipline within government branch > IFSImission and instrument ID > MEXPFSand a 4-digit sequence number > 1001For the number, the first digit represents the VOLUME_SET and thelast number the VOLUME within the VOLUME_SET. Descriptive files ----------------- Descriptive files contain information in order to support the processing and analysis of data files. The following file types are defined as descriptive files with extension eee : .LBL PDS label files .TXT Information (text) filesData Directory Naming Convention and Structure:Inside the DATA directory, the data products are organized intoseveral subdirectories. The structure of the directories will dependupon the phase of the mission in the dataset.IC and NEV:During the Near Earth Verification (NEV) and Interplanetary Cruise(IC) phases of the mission, PFS only took measurements of theinternal calibration source (Internal Black Body and Lamp) and ofdeep space. The limited number of observations are simply divided bysensor into the following directory structure:DATA||-NEV| |- LWC [Long Wave detector]| |- SWC [Short Wave detector]Nominal and Extended Mission:For the nominal and extended mission phases at Mars, data will besplit into groups of 10 orbits, whith the following syntax: The base directory will be MARS as all products from these phases will be from the planet. Beneath this, data will be separated into observations from the long-wave (LWC) and short-wave (SWC) sensors. Finally, data will be divided into blocks of 10 orbits using the following taxonomy: ORBXAcronym | Description--------------------------------------------------------------------- ORB | This is fixed and means ORBIT--------------------------------------------------------------------- | This will be the first 3 digits of all | orbits contained in this directory--------------------------------------------------------------------- X | This is fixed and means that inside this directory are data | from orbits YYY0 to YYY9.---------------------------------------------------------------------For example, the directory ORB000X will contain all products fromorbit 0001 to 0009.The DATA subdirectory structure for the nominal mission data willtherefore follow the scheme:DATA||-NEV| || |-LWC| |-SWC||- IC| |-LWC| |-SWC||-MARS| || |-LWC| | |-ORB001X| | |-ORB002X| || |-SWC| | |-ORB001X| | |-ORB002XFile naming Convention:The data products are identified principally by orbit numer anddetector type, following the scheme:PFS____. Orbit number.For the Near Earth Verification and Interplanetary Cruise Phase the field is substituted with the name of the Phase andSub-phase as: : Dw-Phase>.For the files in the CALIB/ directory the field is substitutewith the field, Responsivity or Deep Spaceobservation, and the field, Forward or Reversependulum motion, as: : _--------------------------------------------------------------------- | IC for Interplanetary Cruise Phase | NEV for Near Earth Verification Phase--------------------------------------------------------------------- | C Check Out Sub-phase | D Dry Earth Sub-phase | E Earth Moon Sub-phase (Observation to Earth and Moon) | 1 PS001 Sub-phase (First Switch ON) | 2 PS002 Sub-phase (Calibration) | 3 PS003 Sub-phase (DTM, Pericenter Pass Simulation, | Calibration) | 4 PS004 Sub-phase (FOV, Calibration) | 5 PS005 Sub-phase (Calibration, heating of SW detector) | S Star Calibration Sub-phase | M Mars Crossing Sub-phase | | all the sub-phases refer to a specific PFS test | operation performed during the NEV phases.--------------------------------------------------------------------- | Defines if the instrument is in calibration mode or | in measurement mode: | | CAL Calibration | MEAS Measurement | | For the HK file field is referred to the | corresponding RAW file field.--------------------------------------------------------------------- | indicates the type of data provided: RAW-HK-RAD | | RAW contains interferogram | HK contains the HK information about PFS during the | acquisition | RAD contains radiance spectra (calibrated data only)--------------------------------------------------------------------- | defines the type of the detector used for the | interferogram acquisition: Short wavelength (SW) or Long | wavelength (LW).--------------------------------------------------------------------- | the extension depends on the type of file (LBL for a | label file, DAT for the data product associated with | the label)---------------------------------------------------------------------For Mars:PFS_0010_ MEAS_HK_SW.LBLPFS_0010_ MEAS_HK_SW.DATwould be a PFS product from Mars orbit 0010. It would be a rawcalibration data product from the short wavelength sensor with itsassociated label.For the Near Earth Verification and Interplanetary Cruise Phase:PFS_NEV1_MEAS_HK_SW.DATPFS_NEV1_MEAS_HK_SW.LBLwould be a PFS product from the PS001 Sub-phase of the Near EarthVerification phase. It would be a raw calibration product from theshort wavelength sensor with its associated label.PFS_IC_CAL_HK_SW.DATPFS_IC_CAL_HK_SW.LBLwould a PFS product from the Check Out sub-phase of theInterplanetary Cruise. It would be a raw calibration product from thelong wavelength sensor with its associated label.Ancillary Data - EXTRAS:The EXTRAS directory contains items that may be useful to a user, butare non-essential for the use of the data in the PFS data sets andare not essential for the PSA or compliance to the PDS Standards.The contents of the EXTRAS directory do not need to conform to PDSstandards, and all files within this directory are produced andpresented by the PFS team. In the PFS EXTRAS directory is a filethat describes any special features of a given orbit. For example,any specific scientific objectives targeted, special events thatoccurred or tests that were completed for a given orbit are listed inthis file. The file is presented in ASCII format.Software:PFS software (tested on IDL version 8)October 2011Set of software able to open and read raw andgeometry data, and to read the right calibration tablesand apply the calibration operation to obtain thecalibrated spectra.When downloading the ZIP file, the user should put it in a working directorydedicated to PFS software,then unzip it.This will create the following subdirectories :||- /CALIB/||- /DATA/||- /FUNCTIONS/||- /GEOMETRY/The essential functions to open and read the data are in the FUNCTIONSdirectory. The examples programs given in both DATA andGEOMETRY are intended only as reader of the PFS data.The CALIB subdirectory contains both the programs to read calibrated PFSspectra stored in the /CALIB_SAMPLE/ directory at dataset root level andthe code to produce that outputs starting from the RAW data and thecalibration tables stored in the /CALIB / directory at dataset root level.To run example code do the following steps:- set working directory as current idl directory- open the main procedure- compile source files by running TWO TIMES the following command in the Command Input Prompt: IDL> @buildAll- execute the main procedureThe LWC_CAL.pro, SWC_CAL_LASER-OFF.pro and SWC_CAL_LASER-ON.pro will give tothe user the calibrated spectra calculated directly from the raw data andfrom the calibration tables.:Functions general usage description:Using the SOFTWARE/DATA/Data_Opener.pro, you can read both RAW data andHK data.1.
