pipeline.infrastructure.utils.imaging

The imaging module contains utility functions used by the imaging tasks.

TODO These utility functions should migrate to hif.tasks.common

Functions

chan_selection_to_frequencies(img, selection)	Convert channel selection to frequency tuples for a given CASA cube.
equal_to_n_digits(x, y[, numdigits])	Approximate equality check up to a given number of digits.
freq_selection_to_channels(img, selection)	Convert frequency selection to channel tuples for a given CASA cube.
intersect_ranges(ranges)	Compute intersection of ranges.
intersect_ranges_by_weight(ranges, delta, …)	Compute intersection of ranges through weight arrays and a threshold.
merge_ranges(ranges)	Merge overlapping and adjacent ranges and yield the merged ranges in order.
set_nested_dict(dct, keys, value)	Set a hierarchy of dictionaries with given keys and value for the lowest level key.
spw_intersect(spw_range, line_regions)	This utility function takes a frequency range (as numbers with arbitrary but common units) and computes the intersection with a list of frequency ranges defining the regions of spectral lines.
update_beams_dict(dct, udct)	Update a beams dictionary.
update_sens_dict(dct, udct)	Update a sensitivity dictionary.
