Update on Gain change findings

Updated on Mon, 2010-06-28 16:59. Originally created by znault on 2010-06-28 16:59.

Nathaniel has been able to compare all the grouped runs and generated gain ration plots to see how they change over the whole run. These groups are noted in the excel spreadsheet attached.

Fitting the Pre and Post

Updated on Mon, 2010-06-28 16:50. Originally created by znault on 2010-06-28 15:10.

We have been able to run through fitting of the pre and post. The file used for this is fitPrePost.C. It finds the summed histogram files that where created after you masked out the bad strips.

The ADC distribution (black) and led ADC distribution (red) is shown for each FMS cell in

STAR/files/userfiles/1651/file/adc.pdf

There is 1 histogram for each cell and the histograms have names that are printed with a c statement like 

printf("ADCr%d_c%d_d%d \n",row,col,nstb-1);

 

row ranges from 0 (top small) to 23 (bottom small)

row ranges from 0 (top large) to 33 (bottom large)

col ranges from  0 (center) to 11 (outside edge small)

col ranges from 0 (center) to 16 (outside edge large)

 

Bit Shifting (unlike other plots on this page, in this plot the top of the plot is the lower part of the FMS!!
