The constraints obtained
by several authors (Eke et al. 1998; Henry [CITE])
on the estimated values of 
, n and 
are revisited in the light of recent theoretical developments: 1) new theoretical mass functions; 2) a more accurate mass-temperature relation, also determined for arbitrary and 
.
I re-derive the X-ray Temperature Function (XTF), similarly to Henry ([CITE]) and Eke et al. (1999), re-obtaining the constraints on , n, .
The result shows that changes in the mass function and M–T relation produces an increase in of 
and similar results in and n.
Key words: cosmology: theory / large-scale structure of Universe / galaxies: formation
