Second Quito Astrolabe Catalogue

Listed in IVOA Registry (Virtual Observatory)

Description

The paper contains 515 individual corrections {DELTA}{alpha} and 235 corrections {DELTA}{delta} to FK5 and FK5Supp. stars and 50 corrections to their proper motions computed from observations made with the classical Danjon astrolabe OPL-13 at Quito Astronomical Observatory of Ecuador National Polytechnical School during a period from 1964 to 1983. These corrections cover the declination zone from -30{deg} to +30{deg}. Mean probable errors of catalogue positions are 0.047" in {alpha}cos{delta} and 0.054" in {delta}.

The systematic trends of the catalogue {DELTA}{alpha}{alpha}cos{delta}, {DELTA}{alpha}{delta}cos{delta}, {DELTA}{delta}{alpha}, {DELTA}{delta}{delta} are presented for the observed zone.
