Recalibrated turbulence profiles at San Pedro Mártir

the calibration of optical turbulence 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 profiles measured with a generalized scidar at the observatorio astronómico nacional of san pedro mártir. the median corrected profile conserves its overall vertical shape. the altitude-averaged ratio of the corrected median 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.
