I was running a catalog_matching file, I got the following error:

Traceback (most recent call last): File "catalog_matching.py", line 909, in main() File "catalog_matching.py", line 782, in main pointing = Pointing(pointing_cat, pointing, survey_name, ra_center, dec_center, fov) File "catalog_matching.py", line 223, in init self.cat = catalog[catalog['Quality_flag'] == 1] File "/home/banele/anaconda3/lib/python3.8/site-packages/astropy/table/table.py", line 1872, in getitem return self.columns[item] File "/home/banele/anaconda3/lib/python3.8/site-packages/astropy/table/table.py", line 246, in getitem return OrderedDict.getitem(self, item) KeyError: 'Quality_flag'

Hi, could you also include the command that you are running the script with?

BANELE-MTHEMBU commented 3 months ago

Greetings,

The command I was using to run the script is:

python catalog_matching.py
img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS.app.restored_srl_bdsfcat.fits
RACS --astro --flux

Here, "RACS" is the name of the catalog I want to match with my original data.

Regards, Banele

Thanks! To generate the img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS.app.restored_srl_bdsfcat.fits catalog, did you use the sourcefinding.py script or your own PyBDSF recipe?

The sourcefinding.py script should take care of everything and add the required info to the catalog. Furthermore, it extracts necessary information from the table meta and puts it in the catalog header in order to run catalog_matching.py effectively. You can do this while keeping your catalog intact by running python sourcefinding.py catalog <your_image> --redo_catalog img_cfp2020_1_full_1024ch_J0438-5419.ms_DDFkMS.app.restored_srl_bdsfcat.fits

Hope that helps, but let me know if something is unclear.
