Step Arguments
The picture_frame step has the following optional arguments to control
the behavior of the processing.
--mask_science_regions(boolean, default=True)Mask regions of the image defined by WCS bounding boxes for slits/slices, as well as any regions known to be affected by failed-open MSA shutters.
--n_sigma(float, default=2.0)The sigma-clipping threshold to use when searching for outliers and illuminated pixels to be excluded from use in the artifact scaling process.
--save_mask(boolean, default=False)If set, the background mask constructed by the step will be saved to a file with suffix “pctfrm_mask”.
--save_correction(boolean, default=False)If set, the correction scaled to and subtracted from the input data will be saved to a file with suffix “pctfrm_correction”.
