Abstract:
    The North  Galactic Pole  Canada-France-Hawaii Telescope  Catalogue of
    faint galaxies is  made available.  We provide  positions, photometric
    and structural parameters  for more than  50000 galaxies. The  J and F
    magnitudes  were obtained from IIIaJ and IIIaF CFHT prime focus plates
    respectively.  This catalogue have been used  in many studies of faint
    galaxy  properties. Galaxy counts, colour distributions and clustering
    properties of faint galaxies  have  been  obtained  with  these  data.
    Statistical properties of stars have been studied as well. For details
    refer to Infante  and  Pritchet  (1992ApJS...83..237I),  Pritchet  and
    Infante (1992ApJ...399L..35P),  Infante (1994A&A...282..353),  Infante
    (1994A&AS..107..413I) and Infante and Pritchet (1995ApJ...439..565I).

    The magnitude errors range from:
    +/-0.3mag at J=24 to less than +/-0.1 at J=20
    +/-0.3mag at F=23 to less than +/-0.1 at F=19
    The rms uncertainty in the zero points is 0.022 (J) and 0.038 (F)

Note (1): The intensity-weighted covariance terms are defined in the
     paper; they are related to the size, eccentricity and position
     angle of the galaxy by:
     S = sqrt(Sxx + Syy)
     e = (Syy + sqrt((Sxx-Syy)^2^ + 4 Syx^2^))/(Sxx+Syy)
     tan(PA) = Sxy/((Sxx + Syy)(1+e)/2 - Syy)
Note (2): defines the area enclosed by a given isophote.
    The surface brightness values of the threshold are:
