Speckle interferometry at the Observatorio Astronómico Nacional. IV
We present speckle interlerometric measurements oí binary stars performed during September and October oí 2009 with the 2.1 m telescope of the Observatorio Astronómico Nacional at SPM (México). We report here the results of 200 measurements of 196 pairs with a primary limiting magnitude of V = 12.3. The measured angular separations range from 0".115 to 5".26. Ninety seven pairs have separations less than 1". The mean error in separation is 0".03 and Iº.5 in position angle. The usual 180° ambiguity was corrected for a majority of position angles by comparison with observations performed by other observers.
