Dear David,

That's not read noise, it must be the bias level. You can subtract it off

Hmm, from the user's point of view one cannot determine if it is really
bias, i.e. due to too low pre biasing the pixel cells in order to remove
noise or if it is real read out noise. Please correct if I'm wrong.

Anyway, the performance is ok but the "bias/readout" noise.

If you're working on driving the newer SBIG cameras from Linux, I'd love
to hear about it. I'm thinking about doing that myself.

No problem, David. Watch the following link:

- ALMASW.ACS
- ACS For (non-)ALMA projects: ACS contributed code

After next week I'll upload the final source code release for our
telescope project. The software is integrated into the ACS (ALMA Common
Software, a kind of abstraction and expansion of ACE & TAO) but it should
be an easy job for a programer to grab the main things from it. I'm using
the latest SBIG developer libraries, so that the (hopefully soon arriving)
STL should run flawlessly. But... I have not integrated the filterwheel
yet. This is scheduled for 3rd quarter this year.

Best regards,
Thomas
