ORAC Recipes for UFTI
ORAC-DR Recipes for use with UFTI
The following tables are designed to let you choose a set of
ORAC-DR recipes appropriate for your particular observing requirements.
Once you've selected a few recipes click on the recipe name for a
complete description of what it does and, importantly, what its
requirements are.
N.B. The Requirements listed below are frames that MUST be obtained
PRIOR to use of the recipe. Darks must have the same integration
time as the target frames, and flats must be obtained through the
same filters.
