Astrocut API

astrocut Package

Functions

asdf_cut(input_files, ra, dec[, ...])	Takes one of more ASDF input files (input_files) and generates a cutout of designated size cutout_size around the given coordinates (coordinates).
build_default_combine_function(template_hdu_arr)	Given an array of ImageHdu objects, initialize a function to combine an array of the same size/shape images where each pixel the mean of all images with available data at that pixel.
center_on_path(path, size, cutout_fles[, ...])	Given a moving target path that crosses through one or more cutout files (as produced by cube_cut/tesscut) and size, create a target pixel file containint a cutout of the requested size centered on the moving target given in the providedpath.
cube_cut(cube_file, coordinates, cutout_size)	Takes a cube file (as created by CubeFactory), and makes a cutout target pixel file of the given size around the given coordinates.
cube_cut_from_footprint(coordinates, cutout_size)	Generates cutouts around coordinates of size cutout_size from image cube files hosted on the S3 cloud.
fits_cut(input_files, coordinates[, ...])	Takes one or more FITS files with the same WCS/pointing, makes the same cutout in each file, and returns the result either in a single FITS file with one cutout per extension or in individual fits files.
get_center_pixel(gwcsobj, ra, dec)	Get the closest pixel location on an input image for a given set of coordinates.
img_cut(input_files, coordinates[, ...])	Takes one or more fits files with the same WCS/pointing, makes the same cutout in each file, and returns the result either as a single color image or in individual image files.
normalize_img(img_arr[, stretch, ...])	Apply given stretch and scaling to an image array.
path_to_footprints(path, size, img_wcs[, ...])	Given a path that intersects with a wcs footprint, return one or more rectangles that fully contain that intersection (plus padding given by 'size') with each rectangle no more than max_pixels in size.
ra_dec_crossmatch(all_ffis, coordinates, ...)	Returns the Full Frame Images (FFIs) whose footprints overlap with a cutout of a given position and size.
setup_logger()	Set up a logger for astrocut
