Step Arguments

The wfs_combine step has the following optional arguments.

--do_refine (boolean, default=False)

If set to True, the nominal image offsets computed from the WCS information are refined using image cross-correlation. See the Algorithm section for details.

--flip_dithers (boolean, default=True)

When set to True, the output star in the combined image from the pairs of WFS images will always be at the same pixel location.

--psf_size (float, default=100)

The largest PSF size in pixels to use for the alignment. This is only used when do_refine is True.

--blur_size (float, default=10)

The smoothing that is applied for the initial centroiding. This is only used when do_refine is True.

--n_size (int, default=2)

This controls the size of the box used to interpolate in the input images. Should never need to be changed.
