Seeing Tests

Observations taken to measure stability of galaxy photometry under varying seeing conditions.

For each of 4 standard fields, obtain data in 4 different bins of seeing conditions.

Field Coords <0.7" 0.7-1.1" 1.1-1.5" >1.5"
VVDS 0h ???
VVDS 2h ???
High Density ???
HSTCluster ???

For each seeing condition and each field, take the following sequence of exposures, with few-arcsec dithers between exposures of a given filter:

g r i z Y
2 x 80s 2 x 80s 2 x 100s 2 x 100 s 2 x 50 s
