IFU: Data Reduction Recipes
The following tables describe the UIST IFU 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.
IMPORTANT: Please note that with EXTENDED_SOURCE the observes in an OT sequence (in a “quad”) must be labelled as “Object” and “Sky”, even when sliding a point source between the top and bottom halves of the IFU field of view. With MAP_EXTENDED_SOURCE all observes should be labelled as “Object”. Use the sequences provided in the template library if you’re not sure.
|REDUCE_FLAT||None||Stores as a flat|
|REDUCE_ARC||Flat||Stores as an arc|
|EXTENDED_SOURCE||Flat, arc, standard||For observations with one position and offset to sky|
|EXTENDED_SOURCE_NOSTD||Flat, arc||As above, but with no standard|
|MAP_EXTENDED_SOURCE*||Flat, arc, standard||Map a source with several IFU positions|
|MAP_EXTENDED_SOURCE_NOSTD *||Flat, arc||Map a source without a standard|
*Use these recipes (in preference to EXTENDED_SOURCE) and the associated Template Library Sequence in the OT if you want to dither the on-source frames, e.g. by a few tenths of an arcsecond.
|STANDARD_STAR||Flat, arc||Standard star with offset to sky|
|STANDARD_STAR_NOD_ON_IFU||Flat, arc||Standard star, nodding within the IFU field|
|NIGHT_LOG||None||Generate an ascii log|
