DOCOBO, J. A. et al. Binary Star Speckle Measurements with the 1.52-M Telescope at Calar Alto. Rev. mex. astron. astrofis [online]. 2007, vol.43, n.1, pp.141-147. ISSN 0185-1101.

We present binary star interferometric measurements carried out on 2001 July and 2004 February with our ICCD speckle camera attached to the 1.52-m telescope of the Observatorio Astronómico Nacional at Calar Alto (Almería, Spain). Data comprise 120 observations of 87 systems with the measured angular separations ranging from 0".102 to 6".076. They are used to improve the orbital elements for STT 170 and STF 1670 AB.

Keywords : BINARIES: VISUAL; STARS: INDIVIDUAL (STT 170, STF 1670 AB); TECHNIQUES: INTERFEROMETRIC.
