A number of years ago the author (Stock, 1978) showed that astrometric positions free of magnitude- or color-dependent errors may be obtained from pairs of objective prism plates with opposite dispersion, since these allow monochromatic measurements as well as a restriction of the photographic density range without restricting the range of magnitudes that can be covered. Results from a series of plates taken originally for a radial velocity survey can now be compared with two new catalogues of positions from meridian circle positions, namely the Perth 70 (Høg 1976) and the Santiago 67 (Carrasco 1982) catalogues.
