This work is the seventh study in a series dedicated to investigatingdegeneracies of simultaneous age, mass, extinction, and metallicitydeterminations of partially resolved or unresolved star clusters with HubbleSpace Telescope broadband aperture photometry. In the sixth work (hereafter,Paper I), it was demonstrated that the adaptive aperture photometry, performedto avoid the majority of the projected foreground and background stars fallingwithin the apertures, gives more consistent colour indices for star clusters.In this study, we aim to supplement the homogeneous multi-colour aperturephotometry results published in Paper~I and provide a complete M31 PanchromaticHubble Andromeda Treasury (PHAT) survey star cluster photometry catalogue forfurther analysis. Following Paper I, we used a two-aperture approach forphotometry. The first aperture is the standard one used to measure totalcluster fluxes. The second (smaller) aperture is introduced to avoid the brightforeground and background stars projecting onto the clusters. We selected theradii of smaller apertures to be larger than the half-light radii of theclusters. We present the second part of the star cluster aperture photometrycatalogues for a sample of 1477 star clusters from the M31 PHAT survey notcovered in Paper I. Compared to the M31 PHAT star cluster aperture photometrycatalogue published by Johnson et al., adjustments were made to the clustercentre coordinates, aperture sizes, and sky background levels.
