Excerpt from Zone Catalogue of 20, 843 Stars Included Between 40??? and 52??? of South Declination, Referred to the Equinox, 1900: Derived From Meridian Observations and Photographs Made at the Royal Observatory, Cape of Good Hope On each Sub-zone the plates are arranged at such intervals in ra. As to ensure that no portion of the area involved is excluded.

Between the limits of declination - 41??? to each zone consists of 144 plates, t.e., the centres of consecutive plates are located at intervals of 10 minutes in ra. Those on the even degrees are centred at 01] 0h oh etc., while those on the odd degrees have their centres at 0h 0h etc. Thus there are seven consecutive zones covered by pairs of plates which overlap approximately by quadrants, while in addition there are small marginal strips common to consecutive plates taken on the same degree of declination.
