Required Reading : The format of all VIRTIS data are described in detail by the EAICD document located in the /DOCUMENT directory. VIRTIS team strongly recommends reading this documentation before using the data.   Data Set Overview : This data set contains raw data acquired by the Rosetta Orbiter VIRTIS spectrometer during the Active Payload Checkout 12 phase of the Rosetta mission, which occurred on 25 April 2010 and 01 May 2010, and during the Lutetia Fly-by phase of the Rosetta mission, which occurred on 9-10 July 2010. Detailed information on the data and the target is given in the appendix E of EAICD and in VIR-IAS-TN-018_ISSUE1.PDF and VIR-IAS-TN- 020_ISSUE1.PDF (located in the DOCUMENT directory).   Processing : The data in this data set are raw, CODMAC Level 2 data. As such, no processes have been applied to the data. that file.   Data : The data are in PDS format. A detailed description of the data format is given in the VIRTIS 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 PLANETOCENTRIC coordinate system. These parameters are corrected by planetary and stellar aberrations. Distances are given in km, angles in degrees.   Software : The data can be accessed with the software IDL routines provided and documented in the DOCUMENT directory.

Confidence Level Overview : Data confidence is nominal, meaning that for all data have been validated by the VIRTIS team and found as expected. Any exceptions are noted by the DATA_QUALITY field in the label files.   Review : First submission December 2007.    Data Coverage and Quality : Data quality is good unless otherwise noted by the DATA_QUALITY keyword.   Limitations : No limitations on these data
