sigmanorm: Renormalize mosaic image to uniform pixel-to-pixel rms
Package: xdimsum
Usage
sigmanorm input expmap output
Parameters
- input
- The name of the input image.
- expmap
- The name of the input exposure map image.
- output
- The name of the output normalized image.
Description
SIGMANORM divides the input image input by a factor equal to the square root of the exposure map image expmap divided by the the maximum exposure value to create the output normalized image output which has a uniform pixel-to-pixel rms noise.
SIGMANORM is currently used by the MKMASK task.
Examples
1. Create a normalized input image for a first pass mosaic image.
