Subject: Re: SMA Data Reduction Software Meeting - followup issue

Dear all,

In the meeting I mentioned that I was able to do end-to-end processing
with only minor glitches.
I want to correct that statement.
It turns out that I had issued the uvlin command with a dummy source
name (due to editing error in my pipeline script).
I am surprised that it did not complain about this source name:
"test", and there was no error reported by uvlin:

uvlin vis=test_rx0.usb.tsys.bp select='source(test*)'
chans=10,150,500,700,1500,1700,2000,2400 mode=line order=1
out=testAll.line options=nowindow
UvLin: version 1.0 24-Jan-07
Applying gain corrections to test_rx0.usb.tsys.bp
exit


But on repeating the uvlin with the proper source: DEC68, I get back
the error about too many spectral windows:

uvlin vis=test_rx0.usb.tsys.bp select='source(DEC68)'
chans=10,150,500,700,1500,1700,2000,2400 mode=line order=1
out=testAll.line options=nowindow
UvLin: version 1.0 24-Jan-07
Applying gain corrections to test_rx0.usb.tsys.bp
### Fatal Error [uvlin]:  Too many spectral windows
exit


This is consistent with what JunHui said in the meeting- that he had
not worked at all on uvlin.

In summary, my list of "pipeline" tasks is now as follows:

smalod: OK
prthd: OK
uvindex: OK
smauvplt: OK
(uvplt also OK)
smacheck: OK
qvack: OK
smafix: OK, but still does not work with x axis to be antenna
elevation; works for time on x axis.
smavarplt: OK
smablflag: OK
smauvspec: OK
(uvspec also OK)
uvaver: fails with "too many spectral windows"
smamfcal: OK
smagpplt: OK
uvflag: OK
uvlin: tails with "too many spectral windows"

Subsequent imaging tasks are untested yet since uvlin fails.

Best regards,
Nimesh
