Reduction of CCD observations of visual binaries using the ``Tepui'' function as PSF
429 CCD measurements of relative positions and magnitude differences inV and R photometric bands for 165 visual double and multiple stars aregiven. CCD frames were taken at the 1.52 m Spanish telescope of theSpanish-German Center of Astronomy at Calar Alto (Almería,Spain). During the reduction process a ``Tepui" function was used as thePSF function.Tables 1 and 2 are only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/416/811

A preliminary compilation of DS-programme star positions
A catalog is presented of the double-star-program (DS-program) starpositions, listing right ascensions for 930 DSs and declinations for1225 DSs of the program. The positions were compiled from the observedvalues obtained between 1980 and 1987 with the meridian circles of sixUSSR observatories (the Moscow, Kazan', Kiev, Khar'kov, Odessa, andTashkent Observatories) and the Belgrade Observatory. The measurementsand the treatment of the observational material were performed using therelative method, and the FK-4 system stars were used as reference stars.
