Dear Rene,
I dont understand why this happens?  First of all, thanx a lot for 
helping me in fitting gaussian to ntuples. Now everything is going fine, 
but whenever I have a dataset with numbers greater than one and the 
range of the data numbers(of 400 data points say) for example lies between 
2.3 to 2.6, and I plot an ntuple and fit, I am getting a mean value of 
0.5 something irrelevant to the data that I am feeding in. But when I 
make the numbers to become less than 1,say 0.23 to .26 then I am getting 
relevant results ie the mean is now between the range (0.244).  Is 
that a bug of any of the version b'coz I am using one of the previous 
versions of root.Probably 3.00. How can I get around it? Please reply. 
Thanx,
yours,
Shiva.
