vison.image.pixbounce.get_pixbounce_from_overscan(ccdobj, thresholds=None)¶ Retrieves Hard Edge Respose for all Quadrants of a CCD. Uses the transition from image to overscan (along rows). Averages across rows. Input image should have high image-area fluence but not saturating. Rows can be filtered by average fluence in them via “thresholds” keyword. Do not use on images acquired with irradiated CCDs.
