Description
We present an astrometric catalogue of positions and proper motions
derived from the Carte du Ciel plates of the San Fernando zone,
photographic material with a mean epoch 1901.4 with a limiting magnitude
V ˜ 15. Digitization has been made using a conventional flatbed
scanner. Special techniques have been developed to handle the
combination of plate material and the large distortion introduced by the
scanner. A variety of post-scan corrections are shown to be necessary.
The equatorial coordinates are on the ICRS system defined by Tycho-2.
Comparison with the reference catalog indicates external errors of
0''.2. The UCAC2 Catalogue was used as second-epoch positions to derive
proper motions with a mean accuracy of 1.2 mas/year for the proper
motions for well-measure stars.
