    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_NNN.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.

    This data set contains calibrated data acquired by the Rosetta    
    Orbiter ALICE UV Spectrometer during the Cruise 4-2 mission phase,
    which took place between 2008-10-06 and 2009-09-13. A detailed    
    listing of all Alice observations is given in the observation log 
    file located in the DOCUMENT directory.

    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.

    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

    Although these data have been calibrated and are in physical      
    units, the wavelength scale is unique to each individial
