DATA_SET_DESCRIPTION
Data Set Overview : The Level 3 Burst mode data products are Derived Data Records (DDRs) generated from multiple Level 1 products. Four Level 3 mosaics are produced of each lunar pole (i.e., regions above 70 deg. latitude) Unlike the lower-level products, these are composed of data sets collected during multiple acquisitions. Please see the Mini-RF data product SIS document (MRFLRO_DP_SIS) in the DOCUMENT directory of this archive for additional information on the data files and their format. Parameters : See individual SIS documents, which are located in the DOCUMENT directory, for detailed descriptions of each file contained in this data archive. Processing : The mosaics are produced manually by ingesting the Level 1 stokes (S1) parameter products and the Level 1 circular polarization ratio (CPR) products into the ISIS software provided by the Astrogeology branch of the USGS. A set of 32 pixels per degree (PPD) and 256 PPD S1 and CPR mosaics are provided for each of the poles resulting in a total of 8 image products. Each image product is accompanied by a detached full PDS label and a JPEG browse image. Data : These data are stored in the DATA/SAR/MOSAICS directory on archival volumes. File names are described in MRFLRO_DP_SIS.PDF. Every file in the directory has PDS label. Except for files in the root, the CATALOG and EXTRAS directories, the label is a separate file in the same directory with the same name but a LBL extension.  Reduced-size browse images of each mosaic are provided in the EXTRAS/QUIKVIEW/MOSAICS/ directory within the archive. Coordinate System : The mosaics are produced from Level 1 products which are oriented in reference to the Moon Principle Axis (PA) coordinate system, as realized using NASA's SPICE products (Frames Kernel). Software : No software is included with this archival data set. Media/Format : These products are delivered on a hard-drive or by ftp and not on a specific formatted medium.

CONFIDENCE_LEVEL_NOTE
Overview : Data in this data are collected from orbits around the Moon. Review : This archival data set was reviewed by the LRO Mini-RF Team prior to submission to the Planetary Data System (PDS). Prior to creation of the final version of the archival data set, key elements of the archive were distributed for preliminary review. These included electronic versions of example PDS labels, CATALOG files, and Software Interface Specifications. These materials were distributed to PDS personnel, the experiment investigator, and others, as appropriate. Data Coverage and Quality : Data reported are the minimally processed data received from the spacecraft during five mission phases: Launch, Cruise, Lunar_Orbit_Acquisition, Commissioning, and Exploration_Mission. These mission phases are defined as: Start time End time Phase Name Date (DOY) Date (DOY) ----------------- ---------------- ---------------- LAUNCH 18 Jun 2009 (169) 18 Jun 2009 (169) CRUISE 18 Jun 2009 (169) 23 Jun 2009 (174) LUNAR ORBIT ACQUISITION 23 Jun 2009 (174) 23 Jun 2009 (174) COMMISSIONING 23 Jun 2009 (174) 14 Sep 2009 (257) NOMINAL MISSION 15 Sep 2009 (258) 14 Sep 2010 (257) SCIENCE MISSION 15 Sep 2010 (258) 14 Sep 2012 (258) No Mini-RF data were collected during Launch, Cruise, or Lunar_Orbit_Acquisition phases. The Mini-RF collected data during each of the other two mission phases. During these planned operational periods, the Mini-RF functioned nominally and the data quality was good. A S-Band receive calibration test was conducted on 20 August, 2009. S-Band transmit calibration tests were conducted on 22-23 August, 2009. These calibrations permit the characterization of both transmit polarization purity as well as determining how precisely polarization can be measured by the instrument. Communications demonstration. Mini-RF experiments to demonstrate half-duplex communications were conducted on 16 August and 20 August, 2009. The Mini-RF began collecting data over the lunar south polar region 13 July 2009 to support LCROSS targeting by characterizing the surfaces of permanently shadowed regions. This data collection phase continued until the LCROSS impact on 9 October. 2009. From Oct 14 through Dec. 17, Mini-RF was largely restricted to collecting data over non-polar sites that lie equatorward of 63 degrees latitude North and South. Since 26 December 2010, the Mini-RF instrument has not transmitted the RF energy required to create radar images of the lunar surface. The Mini-RF team looked at the initial 13 collects attempted from that date forward and noted that in all but one collect the data appeared bad, looking like noise. The team continued to attempt data collections at a reduced rate (about 1 collect per day) through January 23, 2011. Products included in this data set made from data collected after 26 December 2010 do not contain scientifically usefull data. Limitations : This data set is produced multiple strips of calibrated data. The source data strips are received from the spacecraft telemetry, ingested into the LRO Missions Operations Center (MOC) and then transferred to the APL Payload Operations Center (POC).
