Hi,

FYI,

I've made movies for master biases, -dome and -twilight (ugri) for the 
past 3 months on the wiki:

http://wiki.astro-wise.org/projects:kids:qualitycontrol#movies

Bottom line is that the dome flats are more (remarkably!) stable (but 
bad in the case of u'). It may be it is just the dependency on rotator 
angle we are seeing, but if Paranal now keeps this angle fixed it is not 
apparent from the later (November) images.

Note:
- Your mileage may vary running these mpgs: Windows Media Player didn't 
seem to like them, but VLC (Windows) and Totem (Linux) ran.
- When a single CCD is missing all CCDs are shifted: this occurs a few 
times.
- The text at the bottom is OMEGACAM.<template.start>.jpg.

Regards,
Ewout
