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. The Alice team strongly recommends reading this documentation before using the data. Data Set Overview : This data set contains uncalibrated data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the Comet Escort 4 mission phase, which took place between 2015-10-22 and 2015-12-31. Processing : The data in this data set are uncalibrated, CODMAC Level 2 data. As such, corrections for detector dead time, dark counts, flatfield, and effective area have not been applied. The primary FITS header contains a list of which corrections have been applied to that file. 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 and Equinox frame of J2000. SUB_SPACECRAFT_LATITUDE, SUB_SPACECRAFT_LONGITUDE are given in the Cheops reference frame. These parameters are computed at time t:START_TIME. Distances are given in km, angles in degrees. The 67P/C-G_CK comet frame is defined by the kernel file, ROS_CHURYUMOV_V01.TF. Software : All FITS readers should be able to successfully read the data. Updates for Volume Version 2 : The main changes in volume version 2 are the inclusion of an updated Rosetta-Alice Experiment User Manual and Rosetta-Alice To Planetary Science Archive Interface Control Document.

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 : The data have undergone a scientific review and all scientific RID's have been addressed. Data Coverage and Quality : Data quality is good unless otherwise noted by the DATA_QUALITY keyword. Limitations : These data have not been calibrated and are in instrumental units.

ABSTRACT_TEXT This data set contains CODMAC Level 2 data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the comet 67P/Churyumov-Gerasimenko Comet Escort 4 mission phase, which took place between 2015-10-22 and 2015-12-31. The current V2.0 data set supersedes the previous V1.0 data set with improved documentation.
