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 Earth Swing-by 3 mission phase, which took place between 2009-09-14 and 2009-12-13.

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. See the CALIBRATION_COOKBOOK.PDF in the DOCUMENT directory for more information. 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 ======== All FITS readers 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. Review ===== Data Coverage and Quality ========================= Data quality is good unless otherwise noted by the DATA_QUALITY keyword. Limitations =========== Although these data have been calibrated and are in physical units, the wavelength scale is unique to each individial file. Thus, care must be taken when comparing one data file to another. The Alice team recommends using the reformatted, calibrated CODMAC level 4 data products, which solves this problem."
