Function Documentation

bool pmSourceLocalSky (  pmSource *  source, psStatsOptions  statsOptions, float  Radius )

pmSourceLocalSky() Measure the local sky in the vicinity of the given source. The Radius defines the square aperture in which the moments will be measured. This function assumes the source pixels have been defined, and that the value of Radius here is smaller than the value of Radius used to define the pixels. The annular region not contained within the radius defined here is used to measure the local background in the vicinity of the source. The local background measurement uses the specified statistic passed in via the statsOptions entry. This function allocates the pmMoments structure. The resulting sky is used to set the value of the pmMoments.sky element of the provided pmSource structure. Parameters: source  The input image (float) statsOptions  The statistic used in calculating the background sky Radius  The inner radius of the square annulus to exclude

bool pmSourceLocalSkyVariance (  pmSource *  source, psStatsOptions  statsOptions, float  Radius )

Parameters: source  The input image (float) statsOptions  The statistic used in calculating the background sky Radius  The inner radius of the square annulus to exclude
