Digital Camera detector sizes and noise characteristics

The following sites contain some useful information regarding the physical sizes of certain digital camera CCDs, pixel sizes in microns, and noise characteristics and gains at different ISO levels.

Why is this important? Its related to a project I'm working on at the moment. This kind of information is very difficult to find on manufacturer's sites, as they're catering to an audience who has been make to think that number of megapixels is the only metric of value.

Other useful links:
  • dcraw: Read and convert RAW files (of all the various types).
  • rawtran: A wrapper around dcraw to support better conversion of RAw to FITS than the cruder method suggested by dcraw. This is related to the munipack software package.
