This page is a work in project. Please add if you know more or better.

In order of processing:
 * Raw (14 or 15 bits per pixel?  In either case, 2 bytes required.)
  * Straight from the telescope
 * Chip
  * Images:
   * detrended (5 bytes per pixel: 2 signal, 2 weight, 1 mask. Compresses to 44%)
    * flattened
    * debiased
  * Products:
   * PSF measurement
   * point source catalogues
