I just uncovered that for ACA post images when not allowing using the near-field mask to calculate SNR/RMS defaults back to the pre image values rather than the post image values, like what is done for the non-sub-field image. This PR fixes that so that in this case it uses the post_mosaic_SNR and post_mosaic_RMS values instead.
