Scientific paper

The simple, inexpensive method for determining celestial coordinates on original Palomar Schmidt plates developed previously is here inverted and shown to be a useful way of finding and identifying objects with known celestial coordinates. The method is especially suited for rapidly identifying large numbers of radio sources having accurate radio positions which are found in surveys made with large aperture-synthesis instruments. The average position error (approximately 0.9 arc sec) for stellar objects, galaxies, and faint objects near the plate limit is sufficient for making reliable optical identifications of objects as faint as J magnitude = +24 on the basis of position coincidence alone, without regard to color or morphology.
