I think the problem is with the initial values of the fit
parameters.<br>
I suggest you to set initial values by hand for the
sector/superlayer where chi^2 is bad from different sector where
chi^2 is good and then do the fit.<br>
For instance, you have problem with sector 3. Take constants from
sector 4 and use them as initial values for sector 3.<br>

<pre wrap="">Hi All,
At last meeting, I have mentioned the problem about huge CHI-SQ values.
I had changed the Tmax values before fitting to remove them.
However, that way is not solution for this problem.
Even though I use any Tmax values, there is huge number.
You can check the fitting functions and CHI-SQ tables in several Tmax values in the following web:

If you have any idea about this problem, let me know it.
