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.
