find_discontinuity
- jwst.background.background_sub_soss.find_discontinuity(image)[source]
Determine the location of a discontinuity in the background levels.
This function applies a gaussian smoothing filter to the image, then searches for a discontinuity by locating the maximum gradient in the smoothed image. The search is restricted to columns where the discontinuity is expected to occur, set by the
BKG_DISCON_COLUMNSparameter.- Parameters:
- imagendarray
The background template with a discontinuity.
- Returns:
- ndarray
The derived location of the discontinuity in
[x, y].
