Enumeration Type Documentation

enum pmPSFtryMaskValues

pmPSFtryMaskValues The following datatype defines the masks used by the pmPSFtry analysis to identify sources which should or should not be included in the analysis. Enumerator: PSFTRY_MASK_CLEAR  Add comment. PSFTRY_MASK_OUTLIER  1: outlier in psf polynomial fit (provided by psPolynomials) PSFTRY_MASK_EXT_FAIL  2: ext model failed to converge PSFTRY_MASK_PSF_FAIL  3: psf model failed to converge PSFTRY_MASK_BAD_PHOT  4: invalid source photometry PSFTRY_MASK_ALL  Add comment.

Function Documentation

pmPSFtry* pmPSFtryAlloc (  psArray *  sources, char *  modelName, bool  poissonErrors )

pmPSFtryAlloc() Allocate a pmPSFtry data structure.

bool pmPSFtryMetric (  pmPSFtry *  psfTry, float  RADIUS )

pmPSFtryMetric() This function is used to measure the PSF model metric for the set of results contained in the pmPSFtry structure. Parameters: psfTry  Add comment. RADIUS  Add comment.

bool pmPSFtryMetric_Alt (  pmPSFtry *  try, float  RADIUS )

pmPSFtryMetric_Alt() This function is used to measure the PSF model metric for the set of results contained in the pmPSFtry structure (alternative implementation). Parameters: try  Add comment. RADIUS  Add comment.

pmPSFtry* pmPSFtryModel (  psArray *  sources, char *  modelName, float  RADIUS, bool  poissonErrors )

pmPSFtryModel() This function takes the input collection of sources and performs a complete analysis to determine a PSF model of the given type (specified by model name). The result is a pmPSFtry with the results of the analysis.
