Methods Documentation

process(input_data)

Run the Image2Pipeline on the input data.

Parameters:

input_datastr, Level2 Association, or DataModel

The exposure or association of exposures to process.

Returns:

list[JWSTDataModel]

The calibrated data models.

process_exposure_product(exp_product, pool_name=' ', asn_file=' ')

Calibrate an exposure found in the association product.

Parameters:

exp_productdict

A Level2b association product.

pool_namestr

The pool file name. Used for recording purposes only.

asn_filestr

The name of the association file. Used for recording purposes only.

Returns:

JWSTDataModel

The final calibrated product.
