[daip] Fwd: VLA galaxy search

[Patrick Palmer]

Hi Eric,

Bob Gray has two errors.  For the first (IMAGR producing less channels 
than he expected), I told him to go back and check IMAGR inputs carefully.

The second ('software caused network failure'), I have no idea.  Do you 
have any suggestions for him?

Pat

Hi Pat,

I had a long email draft to send to you, which got lost when my main
computer got hit with a malware called CryptoWall 3 that encrypted
everything... not sure if I'll get my stuff back, including the last
month's work.

I'm trying to get some work done at AOC via remote using my backup
laptop, and notice something very odd: the clean image I recently
created has a Freq count of 2 when I do IMHEAD, not the usual 1, and I
wonder if you know what that might mean.   And, the last few 8192
channel cubes I have run SAD on only got to around channel 4060 before
dying (sometimes with a message like 'software caused network failure'
the I don't get at all - on my good machine, as well as on the bad
one).  Any insights you might have would be welcome!

Bob
