Comparison of the sky projected densities of our model to the data in Galactic coordinates (l, b). The top left panel is sky projection of our model where the darkest patches indicate the highest density of RRL. The top-right panel shows the same but convolved with our model for the selection function. The bottom panel shows the equivalent sky projection of the RRL sample used in this work. In general, the sky projected model is similar to the data when convolved with the selection.
