Histogram of the distances to individual variables, projected along the Sun-GC direction. The black histogram shows the 12 965 variables identified by our algorithm, while the light gray histogram shows the 3521 RRab that were added from the OGLE-IV catalog. The latter have a clear bias toward more nearby variables, and therefore, they are excluded from the analysis. The green dotted Gaussian represents the projected bulge density distribution, while the red dotted one refers to the disk. Their sum, reproducing the observed distribution, is the orange thick line. The latter is centered at R_GC=8.30 kpc (blue vertical line).
