- Form: DAOSKY im [BOX=b] [3SIG]
-
- im
- is the image number on which sky is to be determined
- BOX=b
- specfies VISTA box to do calculation in
Returns DAOPHOT's estimate of the modal sky value, or alternatively, an
iterated, 3-sigma rejected mean if the 3SIG keyword is given. It can be
instructive to compare these
with other VISTA estimates (
SKY
,
WSKY
). It is hard to get a good sky value!
