jwst.stpipe Package

JWST implementation of steps and pipelines.

Functions

record_step_status(datamodel, cal_step[, ...])	Record whether or not a step completed in meta.cal_step.
query_step_status(datamodel, cal_step)	Query the status of a step in meta.cal_step.

Classes

Step	alias of JwstStep
Pipeline	alias of JwstPipeline

Base Classes

class jwst.stpipe.core.JwstStep(name=None, parent=None, config_file=None, _validate_kwds=True, **kws)

A JWST pipeline step.

Create a Step instance.

Parameters:

namestr

The name of the Step instance. Used in logging messages and in cache filenames. If not provided, one will be generated based on the class name.

parentStep

The parent step of this step. Used to determine a fully-qualified name for this step, and to determine the mode in which to run this step.

config_filestr or pathlib.Path

The path to the config file that this step was initialized with. Use to determine relative path names of other config files.

_validate_kwdsbool

Validate given kws against specs/config.

**kwsdict

Additional parameters to set. These will be set as member variables on the new Step instance.

class jwst.stpipe.core.JwstPipeline(*args, **kwargs)

A JWST pipeline.

JwstPipeline needs to inherit from Pipeline, but also be a subclass of JwstStep so that it will pass checks when constructing a pipeline using JwstStep class methods.

See Step for the parameters.
