Abstract
The calibration of optical turbulence (CN2) profiles measured with the generalized SCIDAR technique has been recently reviewed and corrected by Avila & Cuevas (2009). Based on that work, here we present the correction of all the CN2 profiles measured with a generalized SCIDAR at the Observatorio Astronómico Nacional of San Pedro Mártir. The median corrected CN2 profile conserves its overall vertical shape. The altitude-averaged ratio of the corrected median CN2 values over the uncorrected ones equals 0.87. The corrected median value of seeing at the site is 0.''68±0.''03, 4.2% lower than the median value obtained with the uncorrected profiles. The median values of the seeing produced by turbulence in the first 2 km above the 1.5 m and the 2.1 m telescopes decrease by 15.8% and 13.6%, respectively. The corrected isoplanatic angle has a median value of 1.''96±0.''04.
