Notes: Column (1): radius interior to which a given quantity is calculated; Col. (2): estimate of the total mass based on the X-ray methodology expressed in units of $10^{11}~M_\odot$ for $\beta =0.35$ (the temperature was taken to be 1 keV in the first bin and 1.30 keV in all the other bins); Col. (3): mass-to-light ratio based on the X-ray methodology in the B-band in solar units for $\beta =0.35$; Col. (4): estimate of the total mass based on the X-ray methodology expressed in units of $10^{11}~M_\odot$ for $\beta =0.50$ (the temperature was taken to be 1 keV in the first bin and 1.30 keV in all the other bins); Col. (5): mass-to-light ratio based on the X-ray methodology in the B-band in solar units for $\beta =0.50$; Col. (6): estimate of the total mass based on the GCs assuming isotropy (see text for details); Col. (7): mass-to-light ratio based on the GCs assuming isotropy in solar units (see text for details); Col. (8): the number of clusters in a given bin.
