Latitude vs. longitude map depicting the position of Sgr GCs in the main body. The colored points highlight the cluster metallicity. Red shows GCs with [Fe/H] ≥ − 0.5, orange shows GCs with −1.0 ≤ [Fe/H] ≤ − 0.6, and blue shows GCs with [Fe/H] ≤ − 1.1 for our convention. We included NGC 6715, Terzan 7, Terzan 8, and Arp 2 for comparison.
