        /SYSTEM systemName

        Name of system for offsets.

        Character :: systemName          ! name of system, one of:
                                         ! PROJECTION
                                         ! TRUEHORIZON

        PROJECTION for now means only the standard simple "radio" projection
        offsets in the chosen coordinate system. This is normally the
        astronomical system of offsets in which point-by-point (TRACK, ONOFF)
        or on-the-fly (OTFMAP) maps are made.

        TRUEHORIZON means the horizontal system with a factor
        1/cos(elevation) applied to the azimuth offset.  This is the system in
        which OTF maps with Wobbler switching and the bolometer are normally
        done.
