Appropriate ORACDR Recipes

The following tables are designed to let you choose a set of IRCAM/TUFTI ORACDR recipes appropriate for your particular requirements. Once you've selected a few recipes click on the recipe name or refer to the next section ORACDR Recipes for more information on what that recipe does, and what its requirements are.

Calibration Recipes
Type Recipe Name Comments
Array check ARRAY_TESTS Calculates readnoise and dark current
Darks REDUCE_DARK Stores as dark
Flats SKY_FLAT Stores as flat, no object masking
  SKY_FLAT_MASKED Masks any objects
  SKY_FLAT_POL Stores a polarimetry flat

Point Source Recipes - Non-Thermal
Type magnitude Recipe Name Comments
V. Bright JHK < 10 BRIGHT_POINT_SOURCE Requires separate flat as ..
Non-thermal   BRIGHT_POINT_SOURCE_APHOT ..background too low to self-flat
Bright 10 < JHK < 15 BRIGHT_POINT_SOURCE  
Non-thermal   JITTER5_SELF_FLAT  
    JITTER5_SELF_FLAT_NOMASK If field uncrowded
    JITTER5_SELF_FLAT_APHOT For point source photometry
    JITTER5_SELF_FLAT_NCOLOUR multiple filters
Faint JHK > 15 JITTER9_SELF_FLAT  
Non-thermal   JITTER9_SELF_FLAT_NOMASK If field uncrowded

Point Source Recipes - Thermal
Type magnitude Recipe Name Comments
Bright L < 10 NOD4_SELF_FLAT_NO_MASK Fast sky removal
Thermal   NOD4_SELF_FLAT_NO_MASK_APHOT For point source photometry
Faint L > 10, all M NOD8_SELF_FLAT_NO_MASK Fast sky removal
Thermal   NOD8_SELF_FLAT_NO_MASK_APHOT For point source photometry

Extended Source Recipes
Type Recipe Name Comments
