pyrex.askaryan.AskaryanSignal.em_shower_RAC

static AskaryanSignal.em_shower_RAC(time, energy)

Calculates R*A_C at the given time and energy.

The R*A_C value is the observation distance R (m) times the vector potential (V*s/m) at the Cherenkov angle. This function calculates the R*A_C values for an electromagnetic shower.

Parameters

timearray_like

Time (s) at which to calculate the R*A_C value.

energyfloat

Energy (GeV) of the shower.

Returns

array_like

The R*A_C value (V*s) at the given time.

pyrex.ARZAskaryanSignal.had_shower_RAC

Calculates R*A_C at the given time and energy.

Notes

Based on equation 16 of the ARZ paper [1]. This parameterization is only described for electromagnetic showers in the paper. For the hadronic shower parameterization see the equivalent hadronic function.
