Abstract:
The results of new reduction of 1545 photographic observations of 14
selected asteroids' obtained with Normal Astrograph of Pulkovo
observatory from 1948 to 1990 years presented. Photographic plates,
stored in observatory's archive, was digitized using consumer flatbed
scanner with special designed technique. The accuracy of measured
photoplates was performed. The UCAC3 was used as reference catalog.
The analysis of instrumental systematic effects, revealing in common
distortion and magnitude equation, was performed and taken into
account. The equatorial coordinates of 1378 single observations of
selected asteroids was obtained and was made their comparison with
results of reduction of this material obtained earlier. 1475 positions
of stars with large proper motions from LSPM catalog was measured
among background objects.
Description:
The results of new reductions of photographic plates, obtained from
1948 to 1990 yr in Pulkovo Observatory during Selected Minor Planets
observation program. There is a 1378 topocentric equatorial positions
of asteroids obtained with var4 reduction and 1475 celestial positions
of LSPM catalogue stars from var5 reduction parameters described in
paper.

Note (1): mpNum is a zero-padded, right-justified number, e.g., an observation
of (1) would be given as 00001, an observation of (3202) would be 03202.
If there is no number these columns must be blank. Six-digit numbers are to
be stored in packed form (A0000 = 100000), in order to be consistent with the
format specifier earlier in this document.
Note on (2): Provisional designation or the temporary designation. The
provisional designation is stored in a 7-character packed form. Temporary
designations are designations assigned by the observer for new or
unidentified objects. Such designations must begin in column 6, should not
exceed 6 characters in length, and should start with one or more letters.
It is important that every observation has a designation and that the same
designation is used for all observations of the same object.
Note (3): Discovery observations for new (or unidentified) objects should
contain "*". Only one asterisked observation per object is expected.
