AEON tests at the beginning of the night (0.5hr)
A short test for linearity measurements after the ToO. (1.0hr)
Starflats. First sets affected by some clouds and should not be used (exposures 1439716 to 1439716). We stopped due to clouds for about 1 hour and made new sets in i, z, g with mostly clear conditions in the direction of the field (but night was non-photometric). Use with care.
