How check TrigObj_filterBits -> 2 = 1e (WPTight)

[vardanaloyan]

Hello dear Experts. In my analysis I want to take Tight Electron L3 trigger objects. I can not find useful information In nanoaod documentation.
https://cms-nanoaod-integration.web.cern.ch/integration/master-102X/mc102X_doc.html#TrigObj
As I understand if i want to take those events which trigger objects are Tight electrons, so i will check the id equals to 11, and filterbit.
Now I am checking filterBits information by this way.
tr.filterBits & (1 << 2) == 1 << 2)
But In another example (GenPart_statusFlags) I want to check 7 : isHardProcess flag. So I did this
ipart_pru.statusFlags & (1 << 7) == 1 << 7
Please explain the correct way to check these 2 flags(trigger filterBits and genParticle statusFlags)

Actually I must check by this way for trigger filterBits (WPTight):
(tr.filterBits & 2) != 0
because 2 in binary representation is "10".
But I am confusing about this statement.
Thanks and Regards!
