Adding the J0137+3309 polcal model

[Sinenhlanhla]

Would it be possible to add J0137+3309 to the known polarisation calibrators? The MeerKAT_Calibrator_Project (
MeerKAT_Calibrator_Project.pdf
) documentation has the model information for this source.

Hi @Sinenhlanhla , I just pushed a new branch (issue1551) with the calibrator properties. Can you try it and let me know?

[Sinenhlanhla]

Hi @francescaLoi, how did you label the branch? When I try to checkout, I get the following error
error: pathspec 'issue1551' did not match any file(s) known to git
I also tried 'issue-1551'

[francescaLoi]

It's there: issue1551

@francescaLoi
Even after moving to the branch
Your branch is up to date with 'origin/issue1551'
I get this error:
2024-02-02 14:59:47 CARACal ERROR: Unable to determine pol_calib=xcal. Is your obsconf section configured properly?Your setting of pol_calib=xcal selects J0137+3309. Supported calibrators are 3C138, 3C286, J1130-1449, J1331+3030, J0521+1638. Alternatively, you can calibrate both leakage and polarization using a (known or unknown) polarized source observed at several parallactic angles. Configure this source as obsconf:xcal, and leakage_calib=pol_calib=xcal. [RuntimeError]

@francescaLoi Thanks, the model has been successfully added.
However, I am now getting the below error

Hi Precious,
can you attach the log?

[Sinenhlanhla]

Hi Francesca.
I've attached it below.

It seems that there is no data between 1005 and 1255 MHz. Maybe these frequency range was flagged? Please check your data.
