An imaging survey of a uniform sample of Brightest Cluster Galaxies and   Intracluster Light
  We present deep, large area B and r' imaging for a sample of 49 brightest cluster galaxies (BCGs). The clusters were selected by their x-ray luminosity and redshift to form two volume limited samples, one with mean redshift ~ 0.07 and one at a mean redshift ~ 0.17. For each cluster the data cover 41' by 41'. We discuss our data reduction techniques in detail, and show that we can reliably measure the surface brightness at the levels of mu_B ~ 29 and mu_r' ~ 28. For each galaxy we present the B and r' images together with the surface brightness profile, B-r' colour, eccentricity and position angle as a function of radius. We investigate the distribution of positional offsets between the optical centroid of the BCG and the centre of the X-ray emission, and conclude that the mass profiles are cuspy, and do not have extended cores. We also introduce a method to objectively identify the transition from BCG to extended envelope of intra-cluster light, using the Petrosian index as a function of radius.
