ObservableValues¶

class ObservableValues : public madspace::FunctionGenerator ¶

Per-event observable values, without binning.

Evaluates one Observable per entry of observables and returns the raw values instead of accumulating them. Unlike ObservableHistograms this keeps the full event sample, so the binning can be chosen afterwards when the generated events are combined.

batch is the leading batch dimension. i indexes the observables.

Arguments

momenta – float, shape (batch, n, 4) – the event momenta.

Returns

value_i – float, shape (batch,) – the value of observable i. An event-level observable returning a vector keeps its own shape.
