Data supplement for paper on Gnuastro's zero point measurement script

Data supplements to the paper titled "Gnuastro: Estimating the Zero Point Magnitude in Astronomical Imaging", published in Research Notes of the American Astronomical Society (RNAAS) journal (arXiv:2312.04263). This paper introduces a recently added program to GNU Astronomy Utilities (Gnuastro). This repository contains all the necessary inputs and output data (listed below). This paper is written in Maneage and its source is available in Codeberg. For more information on how to reproduce this paper, see the README.md and README-hacking.md. The version string e31dd15 (which is imprinted on some file names and hard-coded in others), represents the Git commit used for this publication. The source of this project is also archived in SoftwareHeritage. A brief description of the contents in this repository: paper-e31dd15.pdf: The complete PDF of the paper. sdss-dr12-catalog.fits: SDSS DR12 catalog which overlaps with input image, to find the zero point magnitude with reference catalog (in this paper SDSS catalog is reference catalog). gaia-dr3-overlap-ra-dec.fits: Gaia catalog to use for finding stars in images. 6-arcsec-zp-with-ref-img.txt: Output data files that are used in the demonstration the pink filled circles in left panel of plot in the paper. 2-arcsec-zp-with-ref-img.txt: Output data files that are used in the demonstration the blue filled circles in left panel of plot in the paper. 6-arcsec-zp-with-ref-cat.txt: Output data files that are used in the demonstration the purple filled circles in right panel of plot in the paper. 2-arcsec-zp-with-ref-cat.txt: Output data files that are used in the demonstration the yellow filled circles in right panel of plot in the paper.
