The following tables describe the UIST spectroscopy ORACDR recipes; click on the recipe name for more information. The Requirements listed below are frames that should be obtained prior to use of the recipe, although data can always be re-reduced when the appropriate frames have been taken. Flats and standard stars must be obtained through the same grism and slit.

---

Recipe Name	Requirements	Comments
REDUCE_BIAS	None	Reduce a Bias observation
REDUCE_ARC	None	Stores as an arc
REDUCE_FLAT	Dark	Stores as a flat

---

Recipe Name	Requirements	Comments
POINT_SOURCE	Flat, Arc, Standard star	Default point source reduction
POINT_SOURCE_NOSTD	Flat, Arc	For sources without a standard
POINT_SOURCE_NOFLAT	Arc, Standard star	For sources without a flat
POINT_SOURCE_NOARC	Flat, Standard star	For sources without an arc
POINT_SOURCE_NOFLAT_NOSTD	None	Sources with no flat or standard
FAINT_POINT_SOURCE	Flat, Arc, Standard	For faint targets (weak continuum)

There are versions of these recipes which reduce a standard star sequence; these data are then filed for use with the target observations (see e.g. STANDARD_STAR)
