M31 PHAT clusters aperture photometry

DOI

This work is the seventh study in a series dedicated to investigating degeneracies of simultaneous age, mass, extinction, and metallicity determinations of partially resolved or unresolved star clusters with Hubble Space Telescope broadband aperture photometry. In the sixth work (Naujalis et al., 2021A&A...654A...6N, Cat. J/A+A/654/A6), it was demonstrated that the adaptive aperture photometry, performed to avoid the majority of the projected foreground and background stars falling within the apertures, gives more consistent colour indices for star clusters. In this study, we aim to supplement the multi-colour aperture photometry results published by Naujalis et al. (2021A&A...654A...6N, Cat. J/A+A/654/A6) and provide a complete M31 PHAT survey of star cluster photometry catalogue for further analysis. Following Naujalis et al. (2021A&A...654A...6N, Cat. J/A+A/654/A6), we used a two-aperture approach for photometry. The standard aperture is the one used to measure total cluster fluxes. The smaller aperture is introduced to avoid the bright foreground and background stars projecting onto the clusters. We selected the radii of smaller apertures to be larger than the half-light radii of the clusters. Here we present the second part of the star cluster aperture photometry catalogue for a sample of 1477 star clusters from the M31 PHAT survey not covered in Naujalis et al. (2021A&A...654A...6N, Cat. J/A+A/654/A6), Compared to the M31 PHAT star cluster aperture photometry catalogue published by Johnson et al. (2015ApJ...802..127J, Cat. J/ApJ/802/127), adjustments were made to the cluster centre coordinates, aperture sizes, and sky background levels.
