Abstract
Profiles of surface brightness, ellipticity and position angle
obtained from
CCD-BVRI images are presented for a sample of 14 spiral galaxies with
. 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 
, 
and
show a systematic increase with increasing
apparent ellipticity.
The maximum variation is found for which is
larger for edge-on galaxies than for face-on galaxies.
Key words: galaxies: spiral / galaxies: photometry
Based on observations collected at the South African Astronomical Observatory, Sutherland, Republic of South Africa.
The profile data used for Figs. 1a to 1n are available in electronic form at the CDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or via http://cdsweb.u-strasbg.fr/Abstract.html
