autowisp.processing_steps.stack_to_master module

Class Inheritance Diagram

Stack a collection of images to a master frame.

class autowisp.processing_steps.stack_to_master.ParseAverageAction(option_strings, dest, nargs=None, const=None, default=None, type=None, choices=None, required=False, help=None, metavar=None)

Bases: Action

Parse the specification of the averaging function on the command line.

__call__(parser, namespace, values, option_string=None)

Set the callable to use for averaging.

autowisp.processing_steps.stack_to_master.allowed_interrupted_status_values = (0,)

Frames are marked as started and nothing else until the master is written, so that is the only state an interrupted stack leaves behind.

autowisp.processing_steps.stack_to_master.cleanup_interrupted(interrupted, configuration)

Cleanup file system after partially creating stacked image(s).

autowisp.processing_steps.stack_to_master.get_command_line_parser(*args, default_threshold=(5.0,), single_master=True, default_min_valid_values=5, default_max_iter=20)

Return a command line parser with all arguments added.

autowisp.processing_steps.stack_to_master.get_master_fname(image_fname, configuration, fname_key='stacked_master_fname')

Return the name of the master the given image should contribute to.

autowisp.processing_steps.stack_to_master.main()

Run the step from the command line.

autowisp.processing_steps.stack_to_master.parse_command_line(*args)

Return the parsed command line arguments.

autowisp.processing_steps.stack_to_master.stack_to_master(image_collection, start_status, configuration, mark_start, mark_end)

Stack the given frames to produce a single master frame.

autowisp.processing_steps.stack_to_master.stacking_related_files(image_collection, master_fnames)

The frames going into a stack plus the master(s) coming out.

Unlike the steps that map over their input one file at a time, stacking is the collection: a failure (too few valid frames, mismatched geometry) is about the set, not about one frame, so every input is attached. The set is bounded by what a single master stacks, unlike the per-source lightcurves create_lightcurves writes.

Parameters:

• image_collection – The calibrated frames being stacked.

• master_fnames (Sequence[str]) – The master(s) this stack produces, attached as expected_output – they may not exist yet (or may be half-written) when the failure surfaces.

Returns:

The RelatedFile entries for the stack.

Return type:
