Speckle Interferometry at the Oservatorio Astronómico Nacional: III

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 Astronomico Nacional at SPM (Mexico). We report here the results of 238 measurements of 225 pairs with a p...

Zusammenfassung: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 Astronomico 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 and 1.5° in position angle. Some of the position angles were determined with the usual 180° ambiguity.
