Description:

      SNIPIN allows a user to construct an Infra Red Data Structure (IRDS)
    within GIPSY for test purposes. This is done by asking the user a tape
    containing snipped (by GEISHA programs) IR data. The user will have to
    specify a number of things not available in the FITS headers (e.g. custom
    plate center, coordinate system etc.).

Keywords:

    TAPE=     Name of FITS tape to read [ exit ]

    IRSETOUT= Name of output IR data set [ exit ]

    SKYSYS=   Custom plate coordinate system [ EQUATORIAL ]

    EPOCH=    Epoch of the coordinate system [ 1983.5 ]

    CENTER=   Custom plate center position in degrees [ 0,0 ]

    SIZE=     Custom plate sizes in degrees [ 1,1 ]

    OBJECT=   Name of object in custom plate [ name of IR set ]

    OBSERVER= Name of observer [ ??? ]

    MAXTICKS= Maximum number of satcal ticks [ max number in plate ]

    SNIPS=    Snip numbers wanted in the plate [ all snips on tape ]
