Abstract:
We present the analysis of the spectroscopic and photometric
catalogues of 11 X-ray luminous clusters at 0.07<z<0.16 from the Las
Campanas/Anglo-Australian Telescope Rich Cluster Survey. Our
spectroscopic data set consists of over 1600 galaxy cluster members,
of which two-thirds are outside r200. These spectra allow us to assign
cluster membership using a detailed mass model and expand on our
previous work on the cluster colourmagnitude relation (CMR) where
membership was inferred statistically.
Description:
High-quality broad-band B- and R-band CCD images of our clusters have
been secured at LCO using the 1-m Swope Telescope. More details of the
observations, reduction and analysis of these data are given in
Pimbblet et al. (2001, Cat. J/MNRAS/327/588).

Note (1): Entries with "----" indicate that whilst the R band was observed, the
B band was not (Pimbblet, 2001, Cat. J/MNRAS/327/588)
Note (2): RTDR is the ratio of the height of the fitted peak to the average
height of peaks in the anti-symmetrical part of the cross-correlation
function. The larger the value of RTDR, the better the fit of the
template spectrum to the galaxy spectrum. Since each 2dF fibre is
cross-correlated with many templates, it is necessary to determine
which of the redshift estimates are correct. The redshift is usually
taken to be the value with the highest RTDR.
