1 year ago Note you can also see errors like this for cards that are smaller than expected and end up missing the FRB:
_Error executing process > 'pcal:corr_pcal:loadfits'
Caused by:
Process pcal:corr_pcal:loadfits terminated with an error exit status (1)
(...)
Traceback (most recent call last):

You can check card sizes by going to the work directory and running ls -hs *

This was attributed to the FRB running off the edge of data in card 7 in this case, and so was falling off the edge of the window. Removing the cards affected via going to the config file and adding e.g.:
params.cards = ["1", "2", "3", "4", "5", "6"]
to the config file.
