Abstract (from CDS):

We present astrometric measurements of binary stars based on speckle observations of 164 independent sequences of observations (∼104 frames each) made with the PISCO speckle camera at Pic du Midi. These measurements concern 147 objects, of which 134 were found to be double with a separation in the range 0".1-1".0. These objects were mainly selected among grade 3 orbits to improve the accuracy of their orbits and to constrain their masses. We discovered the binarity of 59 Aql with an angular separation of 0".09±0".01.
