The measurements of stellar angular diameter by photoelectric observation of lunar occultation.
Abstract
Photoelectric occultation traces of SAO 076608 and 076613 have been obtained on 31 Jan., 1985. A preliminary analysis of these occultation traces has been made for an uniform disk. The results show that the angular diameter of SAO is 0arcsec.00173±0arcsec.00018. SAO 076613 is a binary. Its separation in the direction of the Moon's motion and the magnitude difference Δm are Sep = 0arcsec.0078±0arcsec.0007, Δm = 2m.4±0m.2.
