SBC Flats: Super P-flats

The table below shows thumbnails (4x rebinned images) of two "super" P-flats. On the left is shown the super LP P-flat, made by using all the F115LP, F125LP, F140LP, and F150LP thermal vacuum flatfield data (76 frames). On the right the super prism flat is shown. It includes all the PR110L and PR130L data (20 frames). "Bad" areas (the dead annode, unexposed areas) are masked out and set to have a value of 1.0. Click on the image to see a full scale version, and click on the caption to get the gzipped FITS image. Here the display range is between 0.85 and 1.15.
