Data Fields

int centroid
 Centroiding method to use for objects in the field of view. "gaussian" and "moffat" use 2D fits to derive the centroid, "box" is a simple centroid in a square box.
 
const char * centroid_s
 Centroiding method to use for objects in the field of view. "gaussian" and "moffat" use 2D fits to derive the centroid, "box" is a simple centroid in a square box. (as string)
 
double detsigma
 Source detection sigma level to use. If this is negative, values between its absolute and 1.0 are tested with a stepsize of 0.1, to find an optimal solution.
 
double radius
 Initial radius in pixels for pattern matching identification in the astrometric field.
 
double faccuracy
 Factor of initial accuracy relative to mean positional accuracy of the measured positions to use for pattern matching.
 
int niter
 Number of iterations of the astrometric fit.
 
double rejsigma
 Rejection sigma level of the astrometric fit.
 
const char * rotcenter
 Center of rotation of the instrument, given as two comma-separated floating point values in pixels.
 
double lambdamin
 Cut off the data below this wavelength after loading the pixel table(s).
 
double lambdamax
 Cut off the data above this wavelength after loading the pixel table(s).
 
double lambdaref
 Reference wavelength used for correction of differential atmospheric refraction. The R-band (peak wavelength ~7000 Angstrom) that is usually used for guiding, is close to the central wavelength of MUSE, so a value of 7000.0 Angstrom should be used if nothing else is known. A value less than zero switches DAR correction off.
 
int darcheck
 Carry out a check of the theoretical DAR correction using source centroiding. If "correct" it will also apply an empirical correction.
 
const char * darcheck_s
 Carry out a check of the theoretical DAR correction using source centroiding. If "correct" it will also apply an empirical correction. (as string)
