Description:
The tables list the optical and X-rays properties of the RASS-SDSS
galaxy clusters catalog. The catalog contains 114 X-ray selected
systems in the area observed by the Sloan Digital Sky Survey (SDSS).
The X-ray data are taken from the ROSAT All Sky Survey (RASS, IX/10)
while the optical data are taken from the SDSS (J/AJ/123/567)
archive.

Note (1): Erroneous alternative name:
RXCJ0845.3+4430: HGC 35 modified into HCG 35
RXCJ1326.2+0013 was erroneously identified to A1679
RXCJ1627.6+4055: A2127 modified into A2197
RXCJ1640.3+4642: A2199 modified into A2219
RXCJ2324.3+1439 was erroneously identified to A2670,
should be identified to A2593

Note (1): Schechter luminosity function,
φ(M)dM =
0.1ln(10)Ncluφ* x 10^-0.4(M-M*)(alpha-1) x exp(-10-0.4(M-M*)dM
where Nclu is the number of cluster galaxies,
φ* is the normalization of the Schechter luminosity function.
Note (2): The LF luminosity is calculated with the fit based method,
while the LC luminosity is calculated with the galaxy number counts.
