 lan_idf_info
        Return various items of information about the lan IDF.

 Usage:
        lan_idf_info, [channel|head,] <output keys>, <options>


 Argument:
        channel string  input   Specify the channel for which
                                information is required. Needed for
                                channel properties.

 Keywords:
        energy  float   output  A named variable to hold the energy
                                range of the channel [requires
                                channel or head] For a specific
                                channel this is a 3 element array with
                                low, high and "mid-point" for a head
                                it is just the "mid-points".
        geometry float  output  A named variable to return the
                                geometry factor for the channel [needs
                                channel or head]
        background float output A named variable to return the
                                background rates for the channel
                                [needs channel or head]
        pointing float  output  A named variable to return the
                                pointing information for the channel
                                [needs channel or head]
        high_energy float output A named variable to return the high
                                energies for a head [needs head]
        low_energy float output A named variable to return the
                                low energies for a head [needs head]
        sectors int     output  The number of sectors in a head [needs
                                head]
        n_channels int  output  the number of channels in a head
                                [needs head]
        jd_bg_change double output The julian day of the background
                                switch
        doy_bg_change float output The date of the background switch
        have_background int output Whether the IDF has background
                                information.
        version float   output  The version of the IDF file.
        kev             input   If set, then return the energies in
                                keV rather than MeV.
        hiscale         input   If set, then return information from
                                the HISCALE IDF.
        epam            input   If set, then return information from
                                the EPAM IDF.

 Restrictions:
        You can't get channel and head properties in the same call.
        You must give exactly one of the HISCALE or EPAM keys.
