IARDS will send two events back to GO. These two events will contain
solutions from IARDS on determining the local pointing coefficients and
the subreflector Y direction focus position. Examples of these two events are
as follows:
go_aips2-
IARDSpoint([d_az=0.1, d_el=0.1, status=T])
and
go_aips2-IARDSfocus([y=0.1, status=T])
where d_az and d_el are the changes in the pointing coefficients in arcminutes,
y is the subreflector focus position in millimeters and
status indicates that the solution is valid (T) or invalid (F).
