Problems:
Overcast all night, but good for running DECAL scans. We tried new version v4.6 which was supposed to have an option for the N964 filter. However, the option did not exist. Alistair already contacted Marco Bonati about this. We went back to v4.5 for making scans in other filters.

Coarse DECAL scans (steps 10nm) for filters u, g and z. Wavelenght range: 300-1100nm. I have doubts about the results in the u filters since the exposure time (30s, the standard used in previous scans) seemed too low for getting any signal with this filter. Other filters seems ok with that exposure time.
Thanks to Alfredo for helping remotely with the scans at the begining of the night.
Humidity above 95% all night.
