Figure 8.4 shows the significance and relevance plots for all the Side bins used in this
analysis corresponding to all 4 hadron level cuts. The vertical lines indicate the chosen
x rec
1 cut values while the table 8.4 summarises the final choice of the side bin definitions.
Since, as already mentioned, all the Migration bins are subbinned into 2E γ T × 3ηγ bins,
the corresponding Side bins are binned in a similar way.
