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.
