We present near-IR color-magnitude diagrams and physical parameters for a sample of 24 Galactic globular clusters toward the bulge. In this paper we discuss the properties of 12 new clusters (out of the 24) in addition to those previously studied and published by our group. The compilation includes measurements of the cluster reddening, distance, photometric metallicity, horizontal branch red clump, and red giant branch morphological (e.g., mean ridgelines) and evolutionary (e.g., bump and tip) features. The compilation is available in electronic form on the World Wide Web, and it will be updated regularly.

• THE DENSE MATTER EQUATION OF STATE FROM NEUTRON STAR RADIUS AND MASS MEASUREMENTS (2015, methodology): “Two optical and one near-IR studies give consistent and well-constrained distances to NGC 6440: Kuulkers et al. (2003) reported 8.4+1.5−1.3 kpc, Harris et al. (2010) found 8.5 kpc, while Valenti et al. (2007) found 8.2± 0.6 kpc using near-IR data.”
• THE MASS AND RADIUS OF THE NEUTRON STAR IN 4U 1820−30 (2010, background): “Previous studies have yielded two different distance measurements for the globular clus- ter NGC 6624, 7.6 ± 0.4 kpc from optical (Kuulkers et al. 2003) and 8.4 ± 0.6 kpc from near-IR observations (Valenti et al. 2007).”
• THE EQUATION OF STATE FROM OBSERVED MASSES AND RADII OF NEUTRON STARS (2010, unknown): “Güver et al. (2010b) uses a boxcar distribution from 6.8 kpc to 9.6 kpc, to reflect two distance measurements of (7.6± 0.4) kpc (Kuulkers et al. 2003) and (8.4± 0.6) kpc (Valenti et al. 2007).”
• MEASUREMENT OF THE RADIUS OF NEUTRON STARS WITH HIGH SIGNAL-TO-NOISE QUIESCENT LOW-MASS X-RAY BINARIES IN GLOBULAR CLUSTERS (2012, methodology): “…most GCs have distances estimated from photometry – using RR Lyrae variable stars (Marconi et al. 2003; Bono et al. 2007), horizontal branch stars (Valenti et al. 2007; Gratton et al. 2010), or the carbonoxygen white-dwarf (CO-WD) sequence (Hansen et al. 2007) – these methods suffer from…”
• Axion and neutrino bounds improved with new calibrations of the tip of the red-giant branch using geometric distance determinations (2020, background): “[51–54] are very interesting, but they did not provide an explicit I-band TRGB calibration and the uncertainties, especially those from the distances, are not clearly laid out.”
