Step Arguments

The nsclean step has the following optional arguments to control the behavior of the processing.

--mask_spectral_regions (boolean, default=True)

Mask regions in IFU and MOS images that are within the bounding boxes for each slice or slitlet defined in the WCS object of the image.

--n_sigma (float, default=5.0)

The sigma-clipping threshold to use when searching for outliers and illuminated pixels to be excluded from use in the fitting process.

--save_mask (boolean, default=False)

A flag to indicate whether the mask constructed by the step should be saved to a file.

--user_mask (string, default=None)

Path to a user-supplied mask file. If supplied, the mask is used directly and the process of creating a mask in the step is skipped.
