               Testing AIPS++  Detailed Log

April 20-21, 2000, session:

note: TTT = trouble
      BBB = bug
      QQQ = question

After restarting aips++ today I was able to read the 6cm Jupiter ms
that I made yesterday.  

Made a visplot.  Fine.

Tried to make an image but I didn't have setdata and setimage with
matching IF selection so it bombed out on me.

BBB> Couldn't delete the files that imagr left lying around.  
Submitted a bug report on this.

With help from Tim Cornwell, I made an image of Jupiter and was
able to look at it.  

next... self-calibration

BBB> tried to open up an calibrater tool in order to perform
self-calibration.  Task died unexpectedly.

 warning, event glishtk.fail (<task:2>) dropped
LocalExec::SetStatus: abnormal child termination for /home/gtaylor/aips++/linux/bin/glishtk        

and aips++ seems hung.  Starting over...

Calibrater tool started up ok this time.

TTT> Set up self-cal using model generated from initial clean.
Fourier transforming: replacing MODEL_DATA column
Fourier transforms will use image centers as tangent points
made generic SkyEquation
Finished imager::ft
      33.33 real        9.44 user         2.2 system
Selfcalibration failed
and in the Glish window:
"imager_standard.gp", line 61: warning, operand to .solve is not a record
"imager_standard.gp", line 61: error, F is not a function value      

It would be nice to get a bit more information here as to what went
wrong.  Also the documentation for setting up self-calibration 
is woefully inadequate.  I quote
"4. Use the selfcal function to actually perform the gain solution and re-calibration. "
Hey, I could have written this.  What goes in the "model" and what goes in the
"complist"?  Did imager make a model or a complist for me?  How do I view
or touch up the clean component model?  

Anyway, I plotted up both the data and the model in visplot and they 
look good.  Not sure what the problem in selfcal is.  I give up.

--- end of testing.
