What's your machine architecture, ROOT version, BRAT version, BRAG
version, Compiler and Compiler version, Kernel version, and so on.
This information may help in debugging the problem. 

Of special intrest to you two guys in my latest addition to my CVS
area: inspectcalib.cxx - it will show the time evolution of the TMA
and SMA calibrations as present in the ASCII files right now.  I did
this in preperation for submitting the numbers into a real MySQL
database.  

As you'll see, the pedestals and pedestal widths fluctuate some, the
gains and tilts are fairly constant.  For the TMA, the ADC gap seems
to fluctuate quite a lot, while for the SMA, the pulser correction
function seems stable.  Note that only parameters in the ASCII files
are shown, all other are constant (hardcoded in
Br[Tile|Si]TmpCalibration)  

So I propose to make the following revisions: 

  TMA:
    pedestal + pedestalWidth: One for each of the runs 2336, 2338,
                              2339, 2355, 2356, 2357, 2361, 2362,
			      2513, 2517, 2521, 2530, 2535, 2536, plus
			      one for run 1761 
    adcGain:                  One covering run 2336 to 2339 (incl.) and
			      one covering run 2355 to 2362 (incl.) and
			      one covering run 2513 to 2536 (incl.) and
    adcGap:                   One for each of the runs 2336, 2338,
                              2339, 2355, 2356, 2357, 2361, 2362,
			      2513, 2517, 2521, 2530, 2535, 2536, plus
			      one for run 1761 
    tilt:                     One covering run 1761 and   
                              one covering run 2336 to  2536 (incl.)
  SMA: 
    pedestal + pedestalWidth: One for each of the runs 2336, 2338,
                              2339, 2355, 2356, 2357, 2361, 2362,
			      2513, 2517, 2521, 2530, 2535, 2536, plus
			      one for run 1761 
    adcGain:                  One covering run 2336 to 2339 (incl.) and
			      one covering run 2355 to 2362 (incl.) and
			      one covering run 2513 to 2536 (incl.) and
    pulserFunc                One covering run 1761 and   
                              one covering run 2336 to  2536 (incl.)    
    tilt:                     One covering run 1761 and   
                              one covering run 2336 to  2536 (incl.)

For all other parameter, I suggest    

    [other parameters]        One covering run 1761 and   
                              one covering run 2336 to  2536 (incl.)

Having the plots near you will help a lot!

Yours,
