Monitoring the Building Drive Currents

    The program, GET_BLDG, in the KDATA:[SMT.TEST] directory will record the
building drive currents(?) that are wired into channels 25 & 26 of the CAMAC
A/D converter.  It also monitors the antenna azimuth, azimuth tachometer,
and the difference angle between the building and the antenna.  The results
are stored in a file named BLDGddmmmyy.hhmm in KDATA:[SMT.INC] where the
ddmmmyy.hhmm is the day of the month, month abbreviation, 2-digit year,
hour and minute when the program started taking data.  To use it,

	RUN [SMT.TEST]GET_BLDG

It asks for the time interval between averages.  (It reads the A/D about 70
times a second, but Kronen can't write the file faster than about 30 averages
per second.)

It next asks for how many averages to write.

    A GRAPHIC macro reads the data into arrays, TIME, AZ, BLDG1, BLDG2, 
BLDG_ANT, and AZRATE.  (TIME is not stored in the file.  It is calculated
assuming that the requested time between averages was the actual time.)
The macro also plots the data.  To use it,

	SET DEFAULT KDATA:[SMT.INC]
	GRAPHIC
	DEVICE XLAND WHITE
	@GET_BLDG <file>

If you want to read and display only times <Tlow> through <Thigh>, type

	@GET_BLDG <file> <Tlow> <Thigh>
