No clear relation is found between the environment, as characterised by the number of neighbours, and the shape of the profiles of the galaxies.Ībstract = "Using imaging data from the SDSS survey, we present the g' and r' radial stellar light distribution of a complete sample of similar to 90 face-on to intermediate inclined, nearby, late-type (Sb-Sdm) spiral galaxies. Downbending breaks are more frequent in later Hubble types while the fraction of upbending breaks rises towards earlier types. The shape of the profiles correlates with Hubble type. A few galaxies have even a more complex surface brightness distribution. Another similar to 30% shows also a clear break between similar to 4.0-6.0 times the scalelength but followed by an upbending, shallower outer region. About 60% of the galaxies have a break in the exponential profile between similar to 1.5-4.5 times the scalelength followed by a downbending, steeper outer region. The surface brightness distribution of the rest of the galaxies is better described as a broken exponential. Only similar to 10% of all galaxies have a normal/standard purely exponential disk down to our noise limit. The surface brightness profiles are reliable (1s uncertainty less than 0.2 mag) down to mu similar to 27 mag/square".
