Our value is consistent with the one derived from X-ray measurements, namely (3.8 +/- 0.3) 10^22 cm^-2 (Ebisawa et al. 1998). Using the empirical law between the visual extinction and the total column density of hydrogen, Av is found to 19.6 +/- 1.7 mag. This result is 7 mag lower than previously thought, and therefore, a reevaluation of infrared fluxes after derredening is needed.
