Rally,

The camera is an Apogee Alta U16M with D9 body so it is very definitely cooled.

A lot of basic info can be determined from the PTC: full well depth, gain, read noise and Photo Response Non Uniformity. From what I've read (mainly a couple of presentations by Richard Crisp) the data from PTC analysis can be used to determine an appropriate operating temperature for the camera and to determine an optimal flat fielding protocol.

I don't have a calibrated integrating sphere but as far as I can tell all I need is a lightbox and a spreadsheet.

Cheers,
Rick.
