Abstract:
    Into the present catalogue the seasonal mean relative positions (rho
    and theta 2000) are included for 234 visual double stars observed at
    Pulkovo with 26-inch refractor from 1960 through 2001. This catalogue
    is a successor of the catalogue dated 1986 [1].
    Epoch of equinox is 2000.0. The main aim of these observations is to
    create the data base for the double star orbit and mass determinations
    [2]. The stars with the great orbital motion, having longer
    observation series, were measured in the first line.
    The photographic and CCD observations of visual double stars are being
    continued now. The results will be included into the future catalogue.
    Some stars are accompanied with notes. More full information about
    visual double stars investigations in the Pulkovo Observatory may be
    obtained from the articles, the list of references being enclosed.

Note (1): If the star is identified with the WDS star, the coordinates 
    are taken from the WDS catalogue.
Note (2): a new star discovered at Pulkovo.
Note (3): Magnitudes and spectral classes correspond to the WDS.
    If a star is not identified with the WDS star, the visual magnitudes
    are estimated in the system of the Aitken catalogue.
Note (4): In fact it is the number of years were the star was observed
Note (5): Notes:
   ADS 48 ABF (00057+4549) and ADS 11632 (18432+5933) - the measurements
     were made by Dr E.V. Polyakov with the automatic measuring
     complex "Fantazia" [3, 4].
   ADS 497 (00360+2959), 9696 (15292+8027), 9173 (14135+5147),
     10044 (16242+3702), 15600 (22038+6438) - these series were measured
     with the Scanner. The Software was compiled by Dr I.S. Izmailov [5]
   ADS 1090 (01207+4620) - the measurements were made using the
     measuring machine "Parsek" [30].
   ADS 1090 (01207+4620), 9444 (14563+2928), 9573 (15174+4348),

     16693 (23212+3526): WDS 21559+3141 are the optical pairs [6,7,8,9].

Note (1): The sift of bad plates is made in accordance with the 3*sigma
    criterium if the number of plates is more than 4
Note (2): It is determined as  e_tau=rho*e_theta/180
Note (3): Orientation indicator - Indicator of plate orientation needed for
    calculation of theta

    4 = according to a pair of stars with the known coordinates;
    9 = if the mean position is computed using the plates with different
        orientation
Note (4): Observation code:
    1 = A.A. Kiselev
    2 = O.V. Kiyaeva
    3 = O.A. Kalinichenko
    4 = L.G. Romanenko
    5 = N.A. Shakht
    6 = T.P. Kiseleva
    7 = O.P. Bykov
    8 = K.L. Maslennikov
    9 = probationer
    0 = automatic measures
    If the observation series was completed before 1986, then the code 2
       corresponds to Dr G.A. Plugin and the code 4 to Dr B.A. Firago.
    With rare exceptions all plates for each star were measured by only
       one person. In these exceptional cases the code is equal to 11.
