Catalog Service: Speckle interferometry of binaries
Description
We present speckle interferometric measurements of binary stars performed during September and October of 2009 with the 2.1m telescope of the Observatorio Astronomico Nacional at SPM (Mexico). 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 100. The mean error in separation is 0.03" and 1.5{deg} in position angle. The usual 180{deg} ambiguity was corrected for a majority of position angles by comparison with observations performed by other observers.

This is service that does not comply with any IVOA standard but instead provides access to special capabilities specific to this resource.
This is a standard IVOA service that takes as input an ADQL or PQL query and returns tabular data.
This is a standard IVOA service that takes as input a position in the sky and a radius and returns catalog records with positions within that radius.
