RegressAgainstPreviousStep

This step provides a simple way to see how the processing has changed between versions. It will loop over and produce difference images between the current version and the named previous version, so you can see what has changed (and by how much).

API

class pjpipe.RegressAgainstPreviousStep(target, in_dir, curr_version, prev_version=None, file_exts=None, reproject_func='interp', overwrite=False)[source]

Create diagnostic plots to regress against previous versions

Parameters:

  • target – Target to consider

  • in_dir – Input directory

  • curr_version – Current version to compare to…

  • prev_version – Previous version

  • file_exts – File extensions (in priority order) to search for

  • reproject_func – Which reproject function to use. Defaults to ‘interp’, but can also be ‘exact’ or ‘adaptive’

  • overwrite – Whether to overwrite or not. Defaults to False

do_step()[source]

regress_plot(file_dict, key)[source]

Plot per-instrument comparison

Parameters:

  • file_dict – Dictionary of files, separated by instrument

  • key – Instrument key
