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”.
