| Abstract |
At present, the photographic survey by means of the Schmidt
telescope is virtually the only source of information about the
position of faint objects. Since there are no methods of astrometric
reduction of observations that would take into account specific features of
the Schmidt telescope, substantial systematic residual errors prevent
the utilization of Schmidt surveys as a source of information about the
position of faint objects. As shown in [1], the basic source of systematic
errors is that the consequences of the photoplate deformation arising
during the exposure are not taken into account in an adequate way. A
highly accurate method is suggested in [1] for taking into account the
deformation of a square-shaped photoplate. In the present paper, we
investigate another possible source of systematic errors- the
incomplete contact between the deformed photoplate and its spherical
support. It is shown that the incomplete contact may explain the
divergence between the model proposed in [1] for taking into account
systematic errors caused by the deformation of the plate and real
divergences observed in the reduction of Schmidt plates. |
