Description
psphot currently appears to not use the weight map in calculating the background. I was using it on some warped images (warped using SWarp as part of the standard ESSENCE reduction pipeline) where the edges were unfilled and thus represented in the variance map as 1e30. But the background map appears to have fit including those areas. Is this the correct behavior? Did I misinterpret how the background is being fit?
