[daip] fragment of atmca message

[Eric Greisen]

Hello,

I've tried to use the new procedure called ATMCA for our phase-reference experiment
and it finished with the following message

gl1.st> ATMCA1: Task ATMCA  (release of 31DEC06) begins
gl1.st> ATMCA1: Copied CL file from vol/cno/vers  3   75   3 to  3   75   4

gl1.st> ATMCA1: Appears to have ended successfully

How do I interprete the phase "is 40.3 degrees and exceeds the threshold 30 degrees. So the CALIBRATOR is not used with the SOURCE"?
Our calibrators are quite close to BL Lac, about 1 and 5 degrees away.

thanks,
Andrei
