An abstract base class for a plugin that calculates event weights.
This class defines an interface to access event weight and its systematic variations. A derived class must provide an implementation for method ProcessEvent that fills the collection of weights in a way that complies with the specification provided in the documentation for method GetWeights.
| double EventWeightPlugin::GetWeightDown | ( | unsigned | iSource | ) | const |
Returns a "down" systematic variation with the given index.
The indices start from zero. If the given index is larger than the total number of variations, an exception is thrown.
|
noexcept |
Returns a vector with nominal weight and all systematic variations.
The vector is always non-empty and contains an odd number of elements. The first element is the nominal weight, it is followed by an "up" variation for the first source of systematic uncertainty, a "down" variation for this source, and so on.
| double EventWeightPlugin::GetWeightUp | ( | unsigned | iSource | ) | const |
Returns an "up" systematic variation with the given index.
The indices start from zero. If the given index is larger than the total number of variations, an exception is thrown.
|
protected |
Weights assigned to the current event.
The first weight is the nominal one, and it is followed by (optional) systematic variations. Consult documentation for method GetWeights for details.
