摘要：
Starting from an exact definition of the tangential point on Schmidt plates the three azimuthal projections used in Schmidt plate astrometry are compared and plate-tilt effects, which differ from those on astrographic plates, are discussed. It is shown that the azimuthal equidistant projection should be used preferably in Schmidt plate reduction. Practical recommendations are given to minimize the number of significant terms in the reduction model.
