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.
| 2000 A UV imaging of a 6 deg diameter field around MU Aurigae
UV imagery of a 6 deg diameter field centered on Mu Aurigae in thegalactic plane was obtained with the SCAP 2000 experiment dedicated toan UV sky survey. Photometric UV magnitudes at 2000 A are given here formore than 500 stars detected in the field. A star-counting method isapplied to give a fine description of the interstellar matterdistribution up to 1000 pc. The mean space density for B8-A3 stars isderived. Stars with an UV excess are detected and spectralreclassification of some single or binary stars is suggested.
