Description:
The catalog PUL2 was made by photographic method in Pulkovo in
accordance with Deutsch plan (KSZ, Deutch A.N., 1952IAUT....8..789D 1952IAUT....8..789D).
Observations were made using Pulkovo Normal astrograph. The first
epochs of photographic plates were fulfilled since 1937 till 1965,
and the second ones - since 1969 till 1986. PUL2 includes 149 areas
uniformly covering the North sky. The mean epoch difference is 24
years. For each area there are three pairs of plates. All plates are
taken with one hour and 5 min exposure. On the plates with diffraction
grating only bright reference stars were measured. For obtaining
relative star proper motions the faint (15.2) reference stars we
used. Relative proper motions were obtained using a six constant plate
model. For obtaining fictitious proper motions of extragalactic
objects (absolutization) about 700 galaxies was used. Random errors of
relative star proper motions are of 5.5mas/yr in right ascension and
5.9mas/yr in declination. Errors of fictitious proper motions of
galaxies are of 7.9mas/yr (mean absolutization error) for both
coordinates by a representation of the Oort-Lindblad model. On the
base of comparison of the common stars of PUL2 and Hipparcos
catalogues the components of the residual rotation vector of the
Hipparcos referently to extragalactic reference frame have been
derived as follows:
w(x,y,z)=(-0.98,-0.03,-1.66)±(0.47,0.38,0.42)mas/yr.
Mean random errors of absolute bright star proper motions from
comparison of PUL2 and Hipparcos catalogues were estimated as
9mas/yr in both coordinates.

Note (1): Absolute star proper motion must be obtained with formulae:
pmX_absolute = pmX+RX,
pmY_absolute = pmY+RY.
Note (2): Numbers from 1 to 157 are given according to the KSZ plan.
