Spec2Pipeline¶

class jwst.pipeline.Spec2Pipeline(*args, **kwargs)[source]¶

Bases: jwst.stpipe.Pipeline

Spec2Pipeline: Processes JWST spectroscopic exposures from Level 2a to 2b. Accepts a single exposure or an association as input.

Included steps are: assign_wcs, background subtraction, NIRSpec MSA imprint subtraction, NIRSpec MSA bad shutter flagging, 2-D subwindow extraction, flat field, source type decision, straylight, fringe, pathloss, barshadow, photom, resample_spec, cube_build, and extract_1d.

See Step.__init__ for the parameters.

Attributes Summary

`spec`
`step_defs`

Methods Summary

`process`(input)	Entrypoint for this pipeline
`process_exposure_product`(exp_product[, …])	Process an exposure found in the association product
