| 19 | Starting from version 3.0.7 it is possible to test several (up to 32) b-tagging working points for every jet. |
| 20 | The BTag variable in the Jet class can store up to 32 bits. If the user specifies BitNumber = 0 in the BTagging module, that particular bit will be stored in the first position. |
| 21 | If BitNumber = 1, it will be in the second position, etc ... |
