SBC Flats : Raw Ratio Images

The table below shows thumbnails of the ratio of various raw flat images. By raw we mean that they have just been summed, but the detector illumination pattern has not been removed. They are (mostly) normalized to have a mean of 1.0 and are displayed between 0.75 and 1.25. Click on the image to get the full size .gif image.
