Dear Analysts,
I received some old VLA data from the archive recently (from 1982) and ran
into a problem. I loaded the data fine and am doing a PRTAN and the AN
information appears corrupted. It lists only VLA:W4 when the data actually
used the full configuration, and the position of this antenna is
incomplete. Have you had any experience with this problem? I've appended
the PRTAN output to this message.
Can you help or refer me to someone who can? Thanks in advance.
Cheers,
Teddy
