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
