Pointing
the dish with IDL [note: result is zero if dish pointed
correctly]
result=point2(alt=alt, az=az)
result=point2(/home) ; you
only need to do this once when observing begins
alt_limit.pdf (Plot of the minimum altitude
limits for the x-y mount)
alt_limit.sav (IDL save file used to make
alt_limit.pdf)
IDL script to see if pointing to (alt,
az) is allowed by the limits:
restore, 'alt_limit.sav',/verbose
if alt gt alt_limit[round(az)] then r=point2(alt=alt,az=az)
