Similar to Fig. 7, we depict spatial distribution bulge RR Lyrae variables using absolute and mean intensity magnitudes (in I band) together with different methods to account for extinction toward the Galactic bulge. The top three panels show spatial distributions derived using color excesses calculated in this work. The bottom two panels show the same spatial distributions but for distances estimated using literature reddening maps toward the Galactic bulge (from left to right, Nataf et al. 2013; Surot et al. 2020; Gonzalez et al. 2012). To measure individual bar angles we binned spatial dataset into eleven bins between ℓ ≥ −5 and ℓ ≤ 5 deg). As in Fig. 6 we depict measured and zero angles with dashed yellow and dotted black lines, respectively. The χ2 for each fit from top left to bottom right are 0.39, 3.4, 0.37, 1.6, 1.4, and 0.43.
