    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 uncalibrated data acquired by the Rosetta          
    Orbiter ALICE UV Spectrometer during the Rosetta Extension 2 mission      
    phase, which took place between 2016-04-06 and 2016-06-30.

    The data in this data set are uncalibrated, CODMAC Level 2 data.          
    As such, corrections for detector dead time, dark counts, flatfield,      
    and effective area have not been applied. The primary FITS header         
    contains a list of which corrections have been applied to that            
    file.

    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
