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
| Cloudcroft occultation summary. I - December 1978-March 1980
Results are presented from the first 16 months of a program undertakento record lunar occultations at Cloudcroft Observatory. The 85 eventssummarized include 38 observations of stars brighter than seventhmagnitude, 26 reappearances, nine angular diameter measurements, and 11observations of binary stars or stars which may be double.
