Description:
    Profiles of surface brightness, ellipticity and position angle
    obtained from CCD-BVRI images are presented for a sample of 14 spiral
    galaxies with 13<B_T_<16.1. For these galaxies, exponential disc
    components were fitted to the profiles. A decrease of disc
    scalelengths from B to I is found for 13 galaxies, while for one
    galaxy scalelengths increase from B to I. The scalelength ratios
    r_D(B)_/r_D(I)_, r_D(V)_/r_D(I)_ and r_D(R)_/r_D(I)_ show a systematic
    increase with increasing apparent ellipticity. The maximum variation
    is found for r_D(B)_/r_D(I)_ which is 80% larger for edge-on galaxies
    than for face-on galaxies.
