class punchbowl.level3.stellar.PUNCHImageProcessor(layer: int)

Bases: remove_starfield.ImageProcessor

Special loader for PUNCH data.

layer

load_image(filename: str) → remove_starfield.ImageHolder

Load an image.

punchbowl.level3.stellar.generate_starfield_background(filenames: list[str], n_sigma: float = 5, map_scale: float = 0.01, target_mem_usage: float = 1000, reference_time: datetime.datetime | None = None) → [ndcube.NDCube, ndcube.NDCube]

Create a background starfield_bg map from a series of PUNCH images over a long period of time.

punchbowl.level3.stellar.subtract_starfield_background_task(data_object: ndcube.NDCube, starfield_background_path: str | None) → ndcube.NDCube

Subtracts a background starfield from an input data frame.

checks the dimensions of input data frame and background starfield match and subtracts the background starfield from the data frame of interest.

Parameters:

• data_object (NDCube) – A NDCube data frame to be background subtracted

• starfield_background_path (str) – path to a NDCube background starfield map

Returns:

A background starfield subtracted data frame

Return type:

NDCube

punchbowl.level3.stellar.create_empty_starfield_background(data_object: ndcube.NDCube) → numpy.ndarray

Create an empty starfield background map.
