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 reformatted, calibrated data acquired by
    the Rosetta Orbiter ALICE UV Spectrometer during the Rosetta Extension 3
    mission phase, which took place between 2016-07-01 and
    2016-09-30.

  Processing
  ==========

    The data in this data set are reformatted, calibrated CODMAC Level 4
    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. See the CALIBRATION_COOKBOOK.PDF in the DOCUMENT directory
    for more information.

  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, as well as improved browse
    products.

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
  ===========

ABSTRACT_TEXT This data set contains CODMAC Level 4 data acquired by the Rosetta Orbiter ALICE UV Spectrometer during the comet 67P/Churyumov-Gerasimenko Rosetta Extension 3 mission phase, which took place between 2016-07-01 and 2016-09-30. The current V2.0 data set supersedes the previous V1.0 data set with improved browse products and documentation.
