PM decontaminated CMDs for the GC Garro01, showing the VVVX near-IR CMD (top left), the Gaia DR2 optical CMD (top right), and the Gaia-VVVX optical-IR CMDs (bottom panels). Red points are VVVX-Gaia matched sources, while grey points are 2MASS-Gaia matched sources. The black dotted line shows the fit to a PARSEC isochrone with a metallicity of [Fe/H] = −0.70 dex and an age of t = 11.0 Gyr. We note that the well defined cluster RGB and RC are present in all of the CMDs, as is also the case for the residual field contamination on the blue side arising from a fraction of Galactic foreground field stars with similar PMs as the GC.
