Our sample consist of selected seven galaxy clusters from the ROSAT PSPC  Pointed Observations (Vikhlinin et al. 1998) and the revised version by  Mullis et al. 2003 XXX) for this project. (2003).  These had X-ray luminosities in the range $L_{X} \sim 0.5–45 × 10^{43} erg s^{-1}$,   angular core-radius smaller than 60 arcsec and redshifts between 0.18 to 0.70 (for  further details see Paper I, \citep{}).
