DATA_SET_TERSE_DESCRIPTION
DATA_SET_DESCRIPTION Required Reading : The format of all Alice data are described in detail by the EAICD document located in the /DOCUMENT directory. In addition, the Rosetta Alice logbook file, RA_LOGBOOK_NNN.ASC, also located in the /DOCUMENT directory provides observational details such as observation target, commanded exposure time, etc., for all Alice data. The Alice team strongly recommends reading this documentation before using the data. Data Set Overview : This data set contains calibrated data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the Mars swing-by phase of the Rosetta mission, which occurred July 29, 2006 to May 28, 2007. This period includes passive payload checkout #3 (PC3); active payload checkout #4 (PC4); the Mars swing-by observations; and post-sqing-by observations of Jupiter, the Jovian aurora, and the Io plasma torus made in support of the NASA New Horizons mission; and passive payload checkout #5 (PC5). A detailed listing of all Alice observations and their intended targets is given in the observation log file located in the DOCUMENT directory. Processing : The data in this data set are calibrated, CODMAC Level 3 data. As such, corrections for detector dead time, dark counts, flatfield, and effective area have generally been applied. The primary FITS header contains a list of which corrections have been applied to that file. There are some significant discrepancies in the absolute calibration that will be corrected in a subsequent data delivery when the calibration is better understood. Data : The data are in FITS format and text format. Each FITS file has a detached PDS label so that they can be read either by FITS or PDS tools. A detailed description of the data format is given in the ALICE EAICD document located in the DOCUMENT directory of this data set. Ancillary Data : No ancillary data included in this data set. Coordinate System : The geometry items SC_SUN_POSITION_VECTOR, SC_TARGET_POSITION_VECTOR and SC_TARGET_VELOCITY_VECTOR provided in the label of the data product are relative to the Earth Mean Equator frame of J2000. SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in the PLANETOGRAPHIC coordinate system. These parameters are computed at time t:START_TIME. Distances are given in km, angles in degrees. Software : No special software is required to read the data, and all FITS reader routines should be able to successfully read the data.

CONFIDENCE_LEVEL_NOTE Confidence Level Overview : Data confidence is nominal, meaning that all data have been validated by the Alice team and found as expected. Any exceptions are noted by the DATA_QUALITY field in the label files. There are some significant discrepancies in the absolute calibration that will be corrected in a subsequent data delivery when the calibration is better understood. Review : Internal archive review conducted by PDSSBN in December 2008. Data Coverage and Quality : Data quality is good unless otherwise noted by the DATA_QUALITY keyword. Limitations : These data have been calibrated using the best calibration data available at publication time.
