               Testing AIPS++  Detailed Log

Aug 29, 2000, session:

note: TTT = trouble
      BBB = bug
      QQQ = question

I'm still waiting for Athol to produce a PCAL emulator in aips++.

Meanwhile, my bug about the imagerwizard was resolved (I accidently
selected 2 fields).  So I'm trying that out again.

First pass through.  Low resolution image of 1751+096 looked ok,
but the final image was junk.  Now to figure out why...

Second pass through the wizard.  glish and netscape are competing
for all my CPU even though neither one appears to be doing anything
useful for the past 10 minutes.  Killed both and restarted them.

Third pass through the wizard.  Trying a simple Clark clean this time.
0.05"/pixel and 512 pixels.

imager failed to create restored image 1751+096.spw=12.scale=0.33.restored

BBB> And the wizard appears to have abandoned me.  Submitted Bug AOCso01713.

Starting pass number 4 through the wizard...  Tyring Hogbom clean this
time.  Very quick and it works!  Got all the way to my point source
image.  Tried to go back to see how different inputs affect the clark
clean problem above and glish hung up on me again:

LocalExec::SetStatus: abnormal child termination for /home/sneffels3/aips++/stable/linux_egcs/bin/glishtk     

George says this is a longstanding chronic problem of unknown origin.
I'll try to get it to repeat. [-- No luck today --]

Pass number 5 through the wizard.  Trying the mf clean this time.  It 
gives the following severe error:
29-Aug-2000/12:16:09:
Zero Pixels selected with a Fluxlimit of 0.011296 and a maximum Residual of 0.0142603

but produces a reasonable looking image.

The final map, however, looks completely wacky with two negative holes
about as strong as the one positive peak.
