Fig. 4

Distribution of the UV-IR stars (GALEX+WISE+2MASS: dashed-dotted line), GALEX+SDSS stars (dashed line), and model-simulated star counts (solid line) for the AIS field towards the GC, covering 69.9 deg2 of the sky (field 5 in Table 1). The dotted line represents the GALEX+WISE sources with no 2MASS counterparts. The star counts are binned in 0.5 mag interval in NUV magnitude. The error bars in the model-simulated star counts are due to Poisson noise. The NUV 5σ detection limit (NUV magnitude = 20.8) is shown by a solid vertical line. The UV-IR star counts show a turn over at NUV magnitude ~20.5 (demarcated by a dashed vertical line).
