Info

MOPEX User’s Guide is replaced with the median of the neighboring pixel values in exactly the same way the NaN's are replaced in the input images. There is an additional step of re-projection of the shifted images back on the input images, since the outlier detection is performed on the shifted images. A pixel in an outlier image is considered an outlier if the fractional area overlap of the pixel with the outlier pixels from the shifted image is greater than Min Outlier Overlap. 4. Resampling and Combining: For coadding, the input images are resampled and shifted to the common grid using the bicubic interpolation. The ratio of the pixel sizes to the sampling distance is given by the parameters PRF Resample X Factor and PRF Resample Y Factor. The resampled and shifted images are stacked up and a simple mean and standard deviation are found for each pixel position. Output If the Split By Array Position module is included, then the names of the output files are read from the PRF map, in which case the parameters PRF filename and PRF Sigma Filename are ignored if given in the Initial Setup. Otherwise, these parameters can be used to specify the names of the output images with the default names PRF.fits and PRFSigma.fits. A coverage map is output if PRF Coverage Filename is specified in the Initial Settings. 7.5 PRF Estimate Modules The following pages contain full descriptions of the modules that are available in PRF Estimate. Module listing: • Initia l Setup • PRF Estimate Settings • MedFilter • Crop Stack • Split By Array Position • PRF Estimate 7.5.1 PRF Estimate Modules: Initial Setup Command Line Equivalent: None Default Output Directory: N/A De pe nds on: None PRF Estimate 168 PRF Estimate Modules
PURPOSE MOPEX User’s Guide Set up the initial input files for the PRF Estimate flow. You can set either the Input File or the Image Stack file, depending on whether you wish to run PRF Estimate on a single image or a stack of images. INPUT Input File: The single input image to be used to measure the PRF, if you wish to use a single image as input. Either set this or Image Stack File. Image Stack File: The list of images to be used to measure the PRF, if you wish to use a stack of images as input. Either set this or Input File. Point Source List: The list of point sources that you wish to use to calculate the PRF. The table must be in IPAC format, and is usually a source list output by APEX, edited to only include the sources that you wish to use. Output Directory: The output directory that you wish to use for this PRF Estimate run.
