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<BT<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
rD(B)/rD(I), rD(V)/rD(I) and rD(R)/rD(I) show a systematic
increase with increasing apparent ellipticity. The maximum variation
is found for rD(B)/rD(I) which is 80% larger for edge-on galaxies
than for face-on galaxies.
