Notes. Col. 1 galaxy ID; Col. 2 total H-band magnitude; Col. 3 (g − r) color from Iodice et al. (2020); Col. 4 derived (V − H) color used to validate our photometry (see Sect. 5.3); Col. 5 M*/L ratio derived from Into & Portinari (2013); Col. 6 stellar mass derived assuming the absolute solar magnitude MH from Into & Portinari (2013); Cols. 7–9 reports the raw number of GC (
), the corrected for completeness number of GCs (NGC) and the specific frequency (SN); Cols 10–12 reports the dark halo mass estimated using Harris et al. (2017), Moster et al. (2013), Zaritsky & Behroozi (2023) relations, respectively.
