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. | |
Structure to hold the parameters of the muse_flat recipe.
This structure contains the parameters for the recipe that may be set on the command line, in the configuration, or through the environment.
