MDF of the combined bulge sample for different longitude-latitude (l, b) bins, in point-of-view of sky distribution (in Galactic coordinates). The thick lines represent the axes for l and b, i.e. 0° lines with positive (+ve) longitude on the left and negative (-ve) on the right, and -ve latitude downwards and +ve upwards. The red panels represent the central 5 degrees, and the green panels represents the central 10 degrees. Each panel shows the respective lb range, number of stars, and the MDF. Red stars, placed according to their on-sky position, show the metallicity for the Bulge GCs from Souza et al. (2024a). Magenta circles show the median [Fe/H]for the micro-lensed dwarf stars from Bensby et al. (2013). The error bars represent the spread of the [Fe/H]in each lb bins. The blue hexagons show the positions of the fields from the study of Lim et al. (2021), using BDBS bulge red-clump stars.
