Attribute nameAttribute typeDocstringUnit
combinestrType of combination to use {average,median,minmax,sigclip}
fbeamfloatFactor to describe the widening of the beam from the focal plane to photo diode 2.
hsigmafloatHigh sigma for pixel rejection with sigclip
lsigmafloatLow sigma for pixel rejection with sigclip
mergeintMerge output products from different IFUs into a common file.
nhighintNumber of maximum pixels to reject with minmax
nifuintIFU to handle. If set to 0, all IFUs are processed serially. If set to -1, all IFUs are processed in parallel.
nkeepintNumber of pixels to keep with minmax
nlowintNumber of minimum pixels to reject with minmax
object_idoidtypeThe object identifier

The object identifier is an attribute shared by all persistent
instances. It is the prime key, by which object identity is established
overscanstrIf this is "none", stop when detecting discrepant overscan levels (see ovscsigma), for "offset" it assumes that the mean overscan level represents the real offset in the bias levels of the exposures involved, and adjusts the data accordingly; for "vpoly", a polynomial is fit to the vertical overscan and subtracted from the whole quadrant.
ovscignoreintThe number of pixels of the overscan adjacent to the data section of the CCD that are ignored when computing statistics or fits.
ovscrejectstrThis influences how values are rejected when computing overscan statistics. Either no rejection at all ("none"), rejection using the DCR algorithm ("dcr"), or rejection using an iterative constant fit ("fit").
ovscsigmafloatIf the deviation of mean overscan levels between a raw input image and the reference image is higher than |ovscsigma x stdev|, stop the processing. If overscan="vpoly", this is used as sigma rejection level for the iterative polynomial fit (the level comparison is then done afterwards with |100 x stdev| to guard against incompatible settings). Has no effect for overscan="offset".
recipe_versionintVersion of the recipe
savemasterintSave the processed and combined master image before any concolution is done.
savetableintSave the table with all the processed pixel values.
tempfloatLamp temperature [K] used to create the black body function.
