Scientific paper

The paper contains 515 individual corrections {DELTA}α and 235 corrections {DELTA}δ 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 -30deg to +30deg. Mean probable errors of catalogue positions are 0.047" in αcosδ and 0.054" in δ. The systematic trends of the catalogue {DELTA}αalpha_cosδ, {DELTA}αdelta_cosδ, {DELTA}δalpha_, {DELTA}δdelta_ are presented for the observed zone.
