RO-A-CAL-ALICE-4-AST2

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 reformatted, calibrated data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the Lutetia flyby mission phase, which took place between 20100607 and 20100910. A detailed listing of all Alice observations is given in the observation log file located in the DOCUMENT directory. The following Alice observations were made during the period covered by this data set: # Flyby of asteroid (21) Lutetia # 2010 July 513 # Alice activity overview: # * 2010Jul05 12:50:00 AL02 (decontamination; 23 hr, 22 hr heater + 1 hr cooldown) # * 2010Jul06 14:00:00 AL07 (dark calibration; 1 hr) # * 2010Jul06 15:00:00 AL06B, AL03B, AL08B (stellar cal zet Cas; 1 hr each boresight) # * 2010Jul08 14:30:00 AL21A (exosphere search, +26 deg roll; 8 hr 20 min) # * 2010Jul09 03:45:00 AL21B (exosphere search, nominal roll; 5 hr 15 min) # * 2010Jul09 09:15:00 AL21C (exosphere search, 26 deg roll; 9 hr 40 min) # * 2010Jul10 06:45:00 AL21D (exosphere search, nominal roll; 4 hr 40 min) # * 2010Jul10 11:00:00 AL07 (dark calibration; 1 hr) # * 2010Jul10 11:00:00 Breakpoint 2 # * 2010Jul10 12:16:03 AL31 (closest approach obs; 3 hr 49 min) # * 2010Jul10 12:44:53 Asteroid Flyby Mode # * 2010Jul10 15:26:41 Zero Phase # * 2010Jul10 15:44:55.5 Closest Approach (3160 km) # * 2010Jul10 18:30:00 AL09 (boresight alignment, raster scan lam Aql; 1 hr 45 min) # * 2010Jul11 04:45:00 AL32 (closest approa truncated!, Please see actual data for full text [truncated!, Please see actual data for full text]
