Speckle Interferometry at the Observatorio Astronómico Nacional. III
Abstract
We present speckle interferometric measurements of binary stars performed during August of 2010 with the 1.5 m telescope and during November of 2010 with the 2.1 m telescope of the Observatorio Astronómico Nacional at SPM (Mexico). We report here the results of 238 measurements of 225 pairs with a primary limiting magnitude of V = 12.2; 211 of them have separations less than 1''. The mean error in separation is 0.03 arcsec 1.5° in position angle. Some of the position angles were determined with the usual 180° ambiguity.
