 ltacat

	Task to concatenate a number of LTA format files to produce
        one LTA	file.  Various input files will become separate scans 
        in the resultant file.

	The task also looks for "equivalence" of the files being
        concatenated.  All files must be equivalent to the first file
        in the list.  Two files are called "equivalent" if the value
        of the following global	header keywords are equal:

	RECL, DATASIZE, DATA_OFF, PAR_OFF, BASELINE, CHANNELS, LTA,
        INTEG, BASE_NUM, CHAN_NUM

	It also checks to make sure that the antennas used and MAC to
	FFT mapping are compatible.
