Data Fields | |
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 | resample |
The resampling technique to use for the final output cube. | |
const char * | resample_s |
The resampling technique to use for the final output cube. (as string) | |
int | crtype |
Type of statistics used for detection of cosmic rays during final resampling. "iraf" uses the variance information, "mean" uses standard (mean/stdev) statistics, "median" uses median and the median median of the absolute median deviation. | |
const char * | crtype_s |
Type of statistics used for detection of cosmic rays during final resampling. "iraf" uses the variance information, "mean" uses standard (mean/stdev) statistics, "median" uses median and the median median of the absolute median deviation. (as string) | |
double | crsigma |
Sigma rejection factor to use for cosmic ray rejection during final resampling. A zero or negative value switches cosmic ray rejection off. | |
double | lambdamin |
Minimum wavelength for twilight reconstruction. | |
double | lambdamax |
Maximum wavelength for twilight reconstruction. | |
double | dlambda |
Sampling for twilight reconstruction, this should result in planes of equal wavelength coverage. | |
int | xorder |
Polynomial order to use in x direction to fit the full field of view. | |
int | yorder |
Polynomial order to use in y direction to fit the full field of view. | |
double | vignmaskedges |
Pixels on edges stronger than this fraction in the normalized image are excluded from the fit to the vignetted area. Set to non-positive number to include them in the fit. | |
int | vignsmooth |
Type of smoothing to use for the vignetted region given by the VIGNETTING_MASK; gaussian uses (vignxpar + vignypar)/2 as FWHM. | |
const char * | vignsmooth_s |
Type of smoothing to use for the vignetted region given by the VIGNETTING_MASK; gaussian uses (vignxpar + vignypar)/2 as FWHM. (as string) | |
int | vignxpar |
Parameter used by the vignetting smoothing: x order for polyfit (default, recommended 4), parameter that influences the FWHM for the gaussian (recommended: 10), or x dimension of median filter (recommended 5). | |
int | vignypar |
Parameter used by the vignetting smoothing: y order for polyfit (default, recommended 4), parameter that influences the FWHM for the gaussian (recommended: 10), or y dimension of median filter (recommended 5). | |
