Fitting the vertical stellar mass distribution in the 7.8 kpc < R < 8.2 kpc slice with a double sechn function. Different panels are results for different age populations, as marked in the lower left corner. The gray circles are individual measurements of the stellar mass density. Note that measurements with zero density are not presented in the figure. The black filled circles and error bars are volume-weighted mean and standard errors of the mean in vertical bins of 0.05 kpc width. The red curve is the fit, while the blue lines are the individual components of the double sechn function. Residuals of the fitting are plotted in the upper right corner.
