calwebb_wfs-image3: Stage 3 WFS&C Processing

Config

calwebb_wfs-image3.cfg

Class

WfsCombineStep

Stage 3 processing of Wavefront Sensing and Control (WFS&C) images is only performed for dithered pairs of WFS&C exposures. The processing applied is not truly a “pipeline”, but consists only of the single wfs_combine step. The calwebb_wfs-image3.cfg configuration exists only for consistency and compatibility with stage 3 processing of other observing modes. The same result could be obtained by just running the wfs_combine step directly.

Arguments

The calwebb_wfs-image3 pipeline has one optional argument:

--do_refine  boolean  default=False

If set to True, offsets between the dithered images computed from the WCS will be refined emperically using a cross-correlation technique. See wfs_combine for details.

Inputs

2D calibrated images

Data model

ImageModel

File suffix

_cal

The input to calwebb_wfs-image3 is a pair of calibrated (“_cal”) exposures, specified via an ASN file.

Outputs

2D combined image

Data model

ImageModel

File suffix

_wfscmb

The output is a combined image, using the product type suffix “_wfscmb.” See wfs_combine for details on how this combined image is produced.
