Galclaim: A tool to identify host galaxy of astrophysical transient sources

The Galclaim software is designed to identify association between astrophysical transient sources and host galaxy by computing the probability of chance alignment. It is distributed as an open source Python software. It is already used to identify, confirm or reject host galaxy candidates of GRBs and to validate or invalidate transient candidates in astrophysical observations. Such tools are also very useful to characterise archived transient candidates in large sky survey telescopes.
