The b-tag efficiency data-to-simulation scale factor for the MV1 tagging algorithm at 70% efficiency on 8 TeV data, using a tag and probe method based on kinematic selection on ttbar dilepton sample with two jets in the final state. The jets are reconstructed from topological clusters using the anti-kt algorithm with a distance parameter of 0.4, applying the local calibration scheme.

The b-tag efficiency data-to-simulation scale factor for the MV1 tagging algorithm at 70% efficiency on 8 TeV data, using system8 method on muon-jet sample. The jets are reconstructed from topological clusters using the anti-kt algorithm with a distance parameter of 0.4 at the electromagnetic scale and then calibrated to the hadronic scale.
