Notes. Limits of both surveys, numbers of masers (N) and slope of the luminosity function (α) fitted in Sect. 3.1, were applied to our Galactic model; the results are displayed in the columns labeled “Simulation”. The simulated errors correspond to the standard deviation after running 100 simulated galaxies.
