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.
