SwarpSetup.py on fields that are missing images in one or more filters

[SeanPoints]

Run SwarpSetup.py on a field that is missing data from one (or more) filter. For example,

SwarpSetup.py -all LMC_c02 (No N662 data for this field)

Output: The center of this tile is 73.98664 -66.48691 Ha images : 0 SII images : 104 R images : 100 N708 images : 8

@SeanPoints This error should now be fixed on main. Please close the issue, once you have confirmed you no long see this error on any of the fields.

The main issue is fixed, but the program now fails at the SwarpEval stage, because it does not recognize the problem:

No N708 image found

This also seemed to fail for me on LMC_c32

The program no longer falls over when this is the case. I will close this issue shortly.
