Hi Eric,
Walter Max-M. came across a VPLOT bug. He consulted me (its a VLBA satellite-
tracking dataset). I am filing the bug report because he is having keyboard
problems.
vplot, bparm 12,19,1,0; expected it to plot elevation vs. time.
It plots what looks like the correct elevation for antenna 1, but then plots
the same elev. for every antenna. Same behavior for 'TST', 'NEW', 'OLD'. Same
for bparm(2)= 18,19,20,21 (probably) - I can't recall if I tested all of those.
Vplot appears to work fine for the usual bparms amp/phase 12,1,0 or 12,2,0.
