Detailed Description

hold: in particular, "channel" (jet author) aliasing is possible. The difference is that run-time information is to be provided in a text file to be interpreted using ROOT's TEnv and

DB representation (all residing under a common root folder): .../<jet author>="">/<tagger>/<operating point>="">/<flavour>/<object name>=""> where <operating point>=""> can be a weight cut (represented as a string, with the period replaced with an underscore) or the string "Continuous" (for continuous calibration purposes).

This tool provides an interface to flavour tagging performance estimates.

A separate instance should be used for each different tagging algorithm. For each instance, all appropriate jet collections and tagger operating points need to be specified.

The model:

• b-jets: data-MC scale factor (factorised 2D function of eta, pt) MC reference the product is the data efficiency; alternatively, the scale factor may be used
• c-jets: as for b-jets, but with a different MC reference
• light-flavour jets: data-MC scale factor (factorised 2D function of eta, pt) MC reference Besides the results, it is also possible to retrieve associated uncertainties. This need not be configured, and a choice as to the uncertainty component can be made on a case-by-case basis.

To retrieve results from COOL, a CalibrationBroker instance is used (a separate one from the one used for tagger weight distributions). This allows to use the CalibrationBroker's channel aliasing (although possibly with different aliases). Of course it is up to the user to verify that the aliasing is appropriate!
