This MR will add an additional requirement on checking if HLT was active before calculating the tau trigger efficiency in the offline monitoring. This should recover the ~ 0 efficiency observed so far in Physics_Main web display.
In addition, a requirement dR(offline,tau) < 0.3 is applied now both in numerator and denominator efficiency for single leg chains
The effect of this change was checked on :
** efficiency before this change
** efficiency after this change
** efficiency before this change
** efficiency after this change
->-> we see a sizeable effect in data since efficiency denominator now is much smaller compared to previous efficiency definition
