Abstract

Based on the DENIS data observed in a strip passing near to the Galactic anticenter (1=182° - 209°, b=-2° - 13°), and using photometric selection criteria, we extracted a sample of Mira variables. Assuming a spatial distribution in the form of an exponential disk we estimated the scale height using the Maximum Likelihood technique. The procedure also yielded the confidence interval of the estimated parameter.
