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...
