[ascl:2312.027] galclaim: GALaxy Chance of Local Alignment algorIthM

galclaim identifies association between astrophysical transient sources and host galaxy. This association is made by estimating the chance alignment between a given transient sky localization and nearby galaxies. The code can be used with various catalogs, including Pan-STARRS, HSC, AllWISE and GLADE. galclaim also pre-checks for nearby bright galaxy using the RC3 catalog (https://heasarc.gsfc.nasa.gov/w3browse/all/rc3.html). When a nearby galaxy is found, a warning is raised and the properties of the galaxy are saved in a dedicated output file. The package can create plots displaying the computed pval for the found objects for each transient and each catalog; plots are stored in the result/plots directory.
