dc.description.abstractWe present new R-band photometric data for 447 galaxies, gathered for the 'Streaming Motions of Abell Clusters' (SMAC) project. The data comprise 629 individual measurements of the Fundamental Plane (FP) parameters effective radius (R-e) and surface brightness derived from r(1/4)-law profile fitting. More than a third of the galaxies were observed more than once. The photometric precision is similar to0.02 mag as judged from comparisons of aperture photometry between repeat observations of galaxies. The combination X-fp = log R-e - 0.33[mu](e), e, which enters into the Fundamental Plane relation, has internal uncertainties of similar to0.008, corresponding to < 2 per cent in estimated distance. Taken individually, the (correlated) internal errors in R-e and [<mu>](e) are similar to8 per cent and similar to0.12 mag respectively. Comparisons with literature data constrain the external random errors to less than or similar to5 per cent in distance (per observation), which is small in comparison to the similar to 20 per cent scatter in the FR The data will form part of a merged catalogue of FP parameters, presented in a companion paper.
