NuRadioMC.SignalGen.HCRB2017 module

NuRadioMC.SignalGen.HCRB2017.get_time_trace(energy, theta, N, dt, is_em_shower, n_index, R, LPM=True, a=None)[source]

returns the Askaryan pulse in the time domain

Parameters:

energyfloat: energy of the shower
theta: float: viewangle: angle between shower axis (neutrino direction) and the line of sight between interaction and detector
Nint: number of samples in the time domain
dt: float: time bin width, i.e. the inverse of the sampling rate
is_em_shower: bool: true if EM shower, false otherwise
n: float: index of refraction at interaction vertex
R: float: distance from vertex to observer
LPM: bool (default True): enable/disable LPD effect
a: float or None (default Nont): if variable set, the shower width is manually set to this value

NuRadioMC.SignalGen.HCRB2017.get_frequency_spectrum(energy, theta, N, dt, is_em_shower, n, R, LPM=True, a=None)[source]

returns the complex amplitudes of the frequency spectrum of the neutrino radio signal

Parameters:

energyfloat: energy of the shower
theta: float: viewangle: angle between shower axis (neutrino direction) and the line of sight between interaction and detector
Nint: number of samples in the time domain
dt: float: time bin width, i.e. the inverse of the sampling rate
is_em_shower: bool: true if EM shower, false otherwise
n: float: index of refraction at interaction vertex
R: float: distance from vertex to observer
LPM: bool (default True): enable/disable LPD effect
a: float or None (default Nont): if variable set, the shower width is manually set to this value

NuRadioMC.SignalGen.HCRB2017.gauss(x, A, mu, sigma)[source]

NuRadioMC.SignalGen.HCRB2017.get_N_AskDepthA(E, EM=True, LPM=True, fudge_LPM=False)[source]

calculates the Gaussian width (sigma) of the shower profile using the Greisen profile for EM showers and the Gaisser-Hillas profile for HAD showers. If the LPM flag is activated, for EM shower of the shower width of 10.1103/PhysRevD.82.074017 is used.

Please note that the parameterization of the shower width for LPM showers is not compatible with the Greisen parameterization event at regimes where the LPM effect is negligible!!!

Parameters:

E: float: the energy of the shower
EM: bool (default True): switch between EM and had. showers
LPM: bool (default True): enable/disable LPD effect
fudge_LPM: bool (default False): if True, the shower width parameterization of LPM showers is rescaled to match the Greisen parameterization at energies below the E_LPM, i.e., at energies where the LPM effect is negligible
