SPECKLE INTERFEROMETRY AT THE OBSERVATORIO ASTRONÓMICO NACIONAL. I

We present the results of speckle interferometric measurements of binary stars performed in November, 2008 with the 1 m telescope at the Observatorio Astronómico Nacional of Tonanzintla (Puebla, Mexico). The data include 175 position angle and separations measured for 163 systems. The measured angul...

Sumario:We present the results of speckle interferometric measurements of binary stars performed in November, 2008 with the 1 m telescope at the Observatorio Astronómico Nacional of Tonanzintla (Puebla, Mexico). The data include 175 position angle and separations measured for 163 systems. The measured angular separations range from 0.1500 to 4.0000. The maximum magnitude of the brightercomponents is equal to 9.32. The mean error in the separation measurement is 0.0300 and in the position angle is 1'. The majority of position angles were determined with the usual 180' ambiguity, and some of them were corrected by comparison with observations performed by other observers.
