Data Fields

int nifu
 IFU to handle. If set to 0, all IFUs are processed serially. If set to -1, all IFUs are processed in parallel.
 
const char * overscan
 If 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.
 
const char * ovscreject
 This 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").
 
double ovscsigma
 If 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".
 
int ovscignore
 The number of pixels of the overscan adjacent to the data section of the CCD that are ignored when computing statistics or fits.
 
int combine
 Type of combination to use.
 
const char * combine_s
 Type of combination to use (as string)
 
int nlow
 Number of minimum pixels to reject with minmax.
 
int nhigh
 Number of maximum pixels to reject with minmax.
 
int nkeep
 Number of pixels to keep with minmax.
 
double lsigma
 Low sigma for pixel rejection with sigclip.
 
double hsigma
 High sigma for pixel rejection with sigclip.
 
int scale
 Scale the individual images to a common exposure time before combining them.
 
int normalize
 Normalize the master flat to the average flux.
 
int trace
 Trace the position of the slices on the master flat.
 
int nsum
 Number of lines over which to average when tracing.
 
int order
 Order of polynomial fit to the trace.
 
double edgefrac
 Fractional change required to identify edge when tracing.
 
double losigmabadpix
 Low sigma to find dark pixels in the master flat.
 
double hisigmabadpix
 High sigma to find bright pixels in the master flat.
 
int samples
 Create a table containing all tracing sample points.
 
int merge
 Merge output products from different IFUs into a common file.
