Task: uvindex vis = gc_rx1.lsb
The task uvindex
scans a uvdata file and reports changes
in source name, pointing center, number of wideband
and spectral line channels, the observing frequency, and
polarization. This is a useful program and is recommended
for users to run it immediately after the SMA data loaded in Miriad.
It is necessary to check-up the basic information about the
observation before further
processing the data. In addition, the task prthd
gives
the basic information in the header of a uv data file.
