Abstract:
    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.
