    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

    This data set contains reformatted, calibrated data acquired by           
    the Rosetta Orbiter ALICE UV Spectrometer during the Rosetta Extension 2  
    mission phase, which took place between 2016-04-06 and

    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.

    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
