Re: Sky Subtraction Troubleshooting
If the default parameters aren't working for you, the best bet would be to calculate the sky values yourself and feed them to Astrodrizzle using the 'skyfile' parameter. Here's what the help file says regarding this:
skyfile : str (Default = ‘’)
Name of file containing user-computed sky values to be used with each input image. This ASCII file should only contain 2 columns: image filename in column 1 and sky value in column 2. The sky value should be provided in units that match the units of the input image and for multi-chip images, the same value will be applied to all chips.
Another option would be to try Drizzlepac 2.0, which has new algorithms in the Astrodrizzle task to match backgrounds in a situation like yours.
