I/5 Proper Motions in Cape Zone Catalogue -40/-52 (Spencer Jones H.+ 1936)
Proper Motions of Stars in the Zone Catalogue -40 to -52 degrees
of 20843 Stars for 1900
Spencer Jones H. and Jackson J.
<His Majesty's Stationery Office, London (1936)>
ADC_Keywords: Positional data ; Proper motions
Description:
This catalog, listing the proper motions of 20,843 stars
from the Cape Astrographic Zones, was compiled from three series of
photographic plates. The plates were taken at the Royal Observatory,
Cape of Good Hope, in the following years: 1892-1896, 1897-1910,
1923-1928. Data given include centennial proper motion, photographic
and visual magnitude, Harvard spectral type, Cape Photographic
Durchmusterung (CPD) identification, epoch, right ascension and
declination for 1900.

Note on pmRAs, pmRA:
the relation is pmRA = 15 * pmRAs * cos(DE)
if pmRAs is expressed in s/yr and pmRA in arcsec/yr
