Images (craftutils.observation.image)¶

Contains classes representing astronomical images, for performing transformations and processing on them.

Functions¶

craftutils.observation.image.quantity_support(format='latex_inline')

Enable support for plotting astropy.units.Quantity instances in matplotlib.

craftutils.observation.image.fits_table(input_path: str, ...)

Produces and writes to disk a table of .fits files in the given path, with the vital statistics of each. Intended only for use with raw ESO data.

craftutils.observation.image.fits_table_all(input_path: str, ...)

Produces and writes to disk a table of .fits files in the given path, with the vital statistics of each. Intended only for use with raw ESO data. :param input_path: :param output_path: :param science_only: If True, we are writing a list for a folder that also contains calibration files, which we want

to ignore.

Returns¶

craftutils.observation.image.detect_instrument(path: str, ...)

craftutils.observation.image.from_path(path: str, ...)

To be used when there may already be an image instance for this path floating around in memory, and it’s okay (or better) to access this one instead of creating a new instance. When the image may have overwritten a previous file, instantiating the image directly is better.

craftutils.observation.image.expunge()

craftutils.observation.image.register(source, target, ...)

Transform source to coincide pixel to pixel with target.

craftutils.observation.image.cat_columns(cat, f: str | None = None)

Parameters¶

cat

f: str | None = None

Returns¶

craftutils.observation.image.gaussian_distributed_point(x_0, ...)

craftutils.observation.image.solve_field(...)

Returns True if successful (by checking whether the corrected file is generated); False if not. :param image_files: :param base_filename: :param overwrite: :param flags: :param params: :return:

craftutils.observation.image.deepest(img_1: ImagingImage, ...)

craftutils.observation.image.imaging_set_class_dict()

craftutils.observation.image.coadded_set_class_dict()
