MOPEX User’s Guide
This module combines the postage stamp images generated by the Crop Stack module into
the final PRF.
INPUT
Min Number Replacement Pixe ls: (int) The minimum number of pixels neighboring a NaN
to be used for computing the median value that will replace the NaN.
Reject NaNs: (int) The maximum number of NaNs to be replaced before an image is
rejected.
Outlier Threshold: (int) The number of trimmed sigmas below and above the trimmed mean
to determine outliers from the stack of registered, interpolated postage stamps.
Min Outlier Overlap: (float) The fractional overlap between an original pixel and an outlier
pixel in the common, interpolated grid that will trigger rejection of that original pixel.
Max Ratio Outlie rs: (float) The maximum allowable fraction of outlier pixels in an input
postage stamp before that image is rejected. This condition AND the condition for Max
Number Outliers must be exceeded before an image is excluded.
Max Number Outliers: (float) The maximum allowable number of outlier pixels in an input
postage stamp before that image is rejected. This condition AND the condition for Max Ratio
Outliers must be exceeded before an image is excluded.
Flux Column Name: (char) The name of the column in the input point source list
corresponding to the flux of each source. If not given, the flux will be estimated as the sum of
all the pixels within each postage stamp. E.g. flux
PRF Resample X(Y) Factor: (int) The ratio of the input image pixel size to the sampling
distance in the X, Y directions in the final coaddition.
Ze ro Edge : (int) The size in pixels of the margin to the PRF to be set to 0.
PRF Estimate 176
