Variation in best-fit value of the exponent 2/n as a function of fitting range Δz at R = 2 and 8 kpc, where our results for vertical stellar density distribution are fit with a distribution of type sech2/n. The value of 2/n increases with Δz regardless of the disk region, in a similar way. Therefore n cannot be regarded as a robust indicator of density profile.
