Abstract:
    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
    -30° to +30°. Mean probable errors of catalogue positions are
    0.047" in αcosδ and 0.054" in δ. The systematic
    trends of the catalogue {DELTA}ααcosδ,
    {DELTA}αδcosδ, {DELTA}δα,
    {DELTA}δδ are presented for the observed zone.
