RO-CAL-ALICE-2-CR4A

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 uncalibrated data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the Cruise 4A mission phase. All data were obtained as part of the Active Checkout PC8 which occurred during this mission phase. A detailed listing of all Alice observations is given in the observation log file located in the DOCUMENT directory.
