J/A+AS/110/107      Lunar occultations (Meyer+ 1995)

Observations of lunar occultations at Observatoire de la Cote d'Azur Meyer C., Rabbia Y., Froeschle M., Helmer G., Amieux G. <Astron. Astrophys. Suppl. Ser. 110, 107 (1995)> =1995A&AS..110..107M (SIMBAD/NED BibCode)
ADC_Keywords: Occultations ; Stars, double and multiple Keywords: occultations - stars: binaries: general; visual - stars: fundamental parameters Abstract: The results of 114 photoelectric observations are analysed. They were obtained at the two Stations of O.C.A.: Calern and Nice Observatories. We first give a short description of the two photometers used and then we present the interactive reduction method. The astrometric and photometric parameters are derived from each light-curve. Finally we summarize the results and discuss about the non point-like occulted stars: we present 38 double star measurements, for 16 objects, and 11 determinations of angular diameters, for 4 objects.
