niriss_tools.isophotal Package

A subpackage to handle isophotal modelling of galaxies.

This includes alignment and reprojection of all images to the NIRISS reference, and iterative isophote measurements for each image.

Functions

calc_full_var(sci_path, wht_path, exp_path)	Calculate the full variance array from "sci", "wht", and "exp" images.
gen_new_wcs(ref_path[, ref_hdu_index, ...])	Generate a new WCS for a given reference image.
match_photutils(source_psf, target_psf[, ...])	Create a PSF-matching kernel using photutils.
match_pypher(source_psf, target_psf[, ...])	Create a PSF-matching kernel using pypher.
pad_wcs(wcs_in, padding)	Add padding to all relevant WCS keywords.
pc_to_cd(hdr_in)	Convert a PC matrix to a CD matrix.
reproject_and_convolve(ref_path, ...[, ...])	Align, reproject, and PSF match one or more images to a reference.
reproject_image(input_path, output_path, ...)	Reproject an image to a new WCS.
