Use calculated backgrounds and subtract these

Space Telescope Science Institute

Synopsis

Use calculated backgrounds and subtract these from the existing images

Command Line Usage

usage: BackSub.py [-h] [-all] -np 8  field T01 T02 ...

where

* -h gives this documentation
- all causes all tiles in the field to be processed
- np 8  causes 8 procesors to be used

Description

The routine reads the files in the DECam_Prep/field/tile: directory and writes the subtacted in imaages to DECam_Prep2/field/tile

This simply subtracts a background from an image

250201 - For reasons that are unclear the current version of astropy gave an error associated with PCOUNT at this stage. The value for an image should be 0, but was a large number. So I have forced a fix to this.

BackSub.steer(argv): This is just a steering routine
