Notes. Star name (multiple identifiers are listed if present). Unique Gaia DR3 source_id, cross-matched from the SIMBAD database (for all but HD 17505 which is not in Gaia although present in the HIPPARCOS catalog). Region of the W345 complex where the star belongs. BRCs (or pillars) the source is likely ionizing and triggering star formation (from Morgan et al. 2004). The cluster and the corresponding membership probability each source was assigned to, if any. We used the nomenclature introduced by Karr & Martin (2003) for the W5 region.
