Determine source of Nan pixel intensity values #4

Closed STSpencer closed 3 years ago

STSpencer commented 3 years ago

We need to determine why photutils is returning Nan values for certain pixels, particularly near the edge of the camera. This is odd since there's an explicit nan_to_num call in the script that should get rid of any NaNs in the fov map from nsb.

[x] First thing to try is a bigger FoV value in nsb. Note this affects i.e. CDELT1 in fits extraction.

Using a 12 degree fov map in nsb and then using CRDELT values of 0.0012 seems to fix it. Updated parameter spreadsheet.
