NED Abstract

Copyright by Royal Astronomical Society. 2001MNRAS.327..249S Streaming motions of galaxy clusters within 12000 km s^-1^ - II. New photometric data for the Fundamental Plane Russell J. Smith, J.R. Lucey, D.I. Schlegel, Michael J. Hudson, Glenn Baggley and Roger L. Davies Accepted 2001 June 4. Received 2001 June 4; in original form 2000 October 31 ABSTRACT We 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 (<{mu}>_e_), derived from r^1/4^-law profile fitting. More than a third of the galaxies were observed more than once. The photometric precision is ~0.02 mag as judged from comparisons of aperture photometry between repeat observations of galaxies. The combination X_fp_ = log R_e_ - 0.33<{mu}>_e_, which enters into the Fundamental Plane relation, has internal uncertainties of ~0.008, corresponding to < 2 per cent in estimated distance. Taken individually, the (correlated) internal errors in R_e_ and <{mu}>_e_ are ~8 per cent and ~0.12 mag respectively. Comparisons with literature data constrain the external random errors to <~ 5 per cent in distance (per observation), which is small in comparison to the ~20 per cent scatter in the FP. The data will form part of a merged catalogue of FP parameters, presented in a companion paper. Key words: galaxies: clusters: general - galaxies: distances and redshifts - galaxies: elliptical and lenticular, cD - cosmology: observations - large-scale structure of Universe.
