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_VVV.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 second cruise phase of
    the Rosetta mission, which occurred April 5, 2005 to July 28,
    2006. Observations of comet 9/P Tempel 1, calibration targets and
    instrument checkouts were made during this mission phase.
    A detailed listing of all Alice observations is given in the
    observation log file located in the DOCUMENT directory.
 
 
  Processing
  ==========
    The data in this data set are calibrated, CODMAC Level 3 data. 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.  There are some significant discrepancies in the
    absolute calibration that will be corrected in a subsequent
    data delivery when the calibration is better understood.
 
 
  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 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.
 
    There are some significant discrepancies in the
    absolute calibration that will be corrected in a subsequent
    data delivery when the calibration is better understood.

  Data Coverage and Quality
  =========================
    Data quality is good unless otherwise noted by the DATA_QUALITY
    keyword.
 
 
  Limitations
  ===========
    These data have been calibrated and are in physical units
