calwebb_wfs-image2: Stage 2 WFS&C Processing

Config

calwebb_wfs-image2.cfg

Class

Image2Pipeline

Stage 2 processing of Wavefront Sensing and Control (WFS&C) images duplicates the processing applied to regular science imaging, with the exception of image resampling. The calwebb_wfs-image2.cfg configuration utilizes the regular Image2Pipeline module, with the resample step set to be skipped, because the analyis of WFS&C data must be done in the original unrectified image space. The list of steps is shown in the table below.

Arguments

The calwebb_wfs-image2 pipeline does not have any optional arguments.

Inputs

2D countrate data

Data model

ImageModel

File suffix

_rate

The input to Image2Pipeline is a countrate exposure, in the form of “_rate” data. A single input file can be processed or an ASN file listing multiple inputs can be used, in which case the processing steps will be applied to each input exposure, one at a time.

Outputs

2D calibrated data

Data model

ImageModel

File suffix

_cal

The output is a fully calibrated, but unrectified, exposure, using the product type suffix “_cal.”
