Update Processing Versus Magic - Problems and potential solutions

There will not be enough disk space in the IPP cluster to retain all data products for the PS1 survey.

The static sky images and catalogs will be retained but most of the processed images will be deleted sometime after they are processed and perhaps released. The deletion process is known as cleanup. During cleanup enough information is retained so that the pixels can be regenerated. The process of recreating the images is known as update.
