Dear DAIP,
I am now analyzing EVLA data, project code TPOL0002 observed at Jun 22, 2010.
Something wrong happens in CALIB, it seems CALIB overwrite CALCODE.
There are two J1331+3030 in the observation and each of them have
CALCODE 'L' and 'P'.
I would like to CALIB the data using both J1331+3030 (3C286) as CALSOURCE.
However, I was not able to CALIB with error message;
> CALIB1: Task CALIB (release of 31DEC10) begins
> CALIB1: Using $PROJECT$ . XBAND . 2 Disk= 1 Usid= 3001
> CALIB1: L1 Solution type
> CALIB1: Doing no flagging this time
> CALIB1: Selecting and calibrating the data
> CALIB1: A CLEAN MODEL WAS REQESTED FOR MULTIPLE SOURCES
> CALIB1: Purports to die of UNNATURAL causes
> CALIB1: sagittar 31DEC10 TST: Cpu= 149.1 Real= 1452 IO= 3571
Morover, after running CALIB (but failed),
I checked the data using LISTR with OPTY 'SCAN' and CALCODE of J1331 is changed.
Both of them become 'L' or 'P' (it is due to parameter of CALIB).
It seems strange for me and could you give me some advise?
sincerely,
