 uleis_idf_info
        Get information from the ULEIS IDF object (and its attached
        calib objects).

 Usage:
        uleis_idf_info, time, channel, <output keys>

 Argument:
        time    dbl/flt input   The time at which the information is
                                required (can be either a DOY array or
                                a julian day number).
        channel string  input   The channel for which the information
                                is required (e.g. O L 10).


 Keywords:
        cal_times       double  output  The JD's at which the
                                        different calibration files
                                        are valid.
        cal_days        float   output  The same thing in DOY format.
        detectors       int     output  The detectors used by the
                                        specified channel at the
                                        requested time.
        geometry        float   output  The EFFECTIVE geometry of a
                                        a particular channel and time
                                        (this factors in the
                                        efficiency for the species and
                                        the detectors in use).
        energy          float   output  The energy range of the
                                        requested channel at the
                                        requested time.
        centre_energy   float   output  The mid-point energy of the
                                        requested channel at the
                                        requested time.
        channel_list    string  output  The list of channels in a
                                        particular system and time
                                        (needs one of each of the
                                        MATRIX/PAIRS and SMALL/LARGE
                                        keys to be set).
        ending          double  output  The last JD at which the
                                        values returned are valid.

        matrix                          If set then the channel list
                                        is for the Matrix-Singles data.
        pairs                           If set then the channel list
                                        is for the Matrix-Pairs data.
        small                           If set then the channel list
                                        is for the small energy system.
        large                           If set, then the channel list
                                        is for the large energy system.
        kev                             If set then return energies in
                                        keV rather than MeV.
        is_valid        byte    output  Whether or not ULEIS data are
                                        supported at this site.

 Notes:
        If ULEIS data are not available, then the keywords other than
        is_valid are unchanged.
