Calibration (sitelle.calibration)

Description

This module gathers convenient functions that are used during the astrometric calibration of SITELLE data. It defines an astrometric precision method, as well as a cross-matching algorithm. Most of all, it provides wrapper to world2pix and pix2wolrd method using the third astrometric calibration defined by Martin et al. 2018

Functions

filter_star_list(_star_list)	Very basic filter to remove stars position which are out of the image.
fit_stars_from_list(im, star_list_pix[, …])	Wrapper method around orb.utils.astrometry.fit_stars_in_frame().
compute_precision(list0, list1, scale)	Displays the astrometric mean difference between two position lists of the same objects.
world2pix(star_list_deg, wcs[, dxmap, dymap])	Conversion from physical coordinates to pixel coordinates using WCS and eventually dxdymaps.
pix2world(star_list_pix, wcs[, dxmap, dymap])	Conversion from pixel coordinates to physical coordinates using WCS and eventually dxdymaps.
match_star_list(_list0, _list1)	Astrometric cross-match method between two list of objects.
