Bin Migration

Fig.4 Each of 9 (N of pT2bins=9) 3x3 panel contains Mass distribution of pi0 in a given pT2 generated bin and reconstructed everywhere else.
Number in BLUE is N of generated pi0 in this bin. Number in RED is number of reconstructed pi0 calculated from Gaus fit
BLACK distributions & entries in TPaveStat are reconstructed pi0 that were generated in a bin with a blue number
RED distributios and Entries in TPaveStat are total number of reconstructed events in each bin.
NOTE: Reconstructed distributions were extracted using MATCHING technique




Fig.5 Each of three (selected is every fifth generated bin in Z, N bins in Z =15) 3x5 panel contains Mass distribution of pi0 in a given Z generated bin and reconstructed everywhere else
COLOR scheme is the same as for pT2 in Fig.4

Range of generated events.


Choosing folowing kinematic cuts in Lepto would yield following distributions:
User applied cuts (+ phase space) :
9.0000E-02 < x < 1.000
0.000 < y < 1.000
0.8000 < Q**2 < 10.00
3.900 < W**2 < 20.00
1.000 < nu < 5.014

Effective ranges (from above cuts):
9.0000E-02 < x < 0.6791
0.4059 < y < 1.000
0.8000 < Q**2 < 6.390
3.900 < W**2 < 9.443
1.000 < nu < 5.014
