NuRadioReco.utilities.cr_flux.get_analytic_cr_flux(log10_energy, type='auger_19')

Parameters:

log10_energy: float

energies (in log10(E / eV)))

type: string

analytic parametrization of spectrum in NuRadio base units (which are 1/(eV m^2 sr ns)

NuRadioReco.utilities.cr_flux.get_flux_per_energy_bin(log10e_min, log10e_max, type='auger_19')

Returns an scipy integration of the measured data or the analytic spectrum over given interval.

Parameters:

log10e_min: float

Input energy lower bound (in log10(E / eV)))

log10e_max: float

Input energy upper bound (in log10(E / eV)))

type: string

choose between data_auger_19, data_TA_21, auger_17, auger_19, TA_19

NuRadioReco.utilities.cr_flux.get_cr_event_rate(log10energy=18, zenith=0.8726646259971648, a_eff=1, type='auger_19')

Cosmic ray event rate at a specific energy and zenith angle assuming a detector with effective area ‘A_eff’. The detector projection and solid range are taken into account. The flux is calculated with the analytic spectrum.

Parameters:

log10energy: float

energy in units log10(energy/eV)

zenith: float

zenith angle

a_eff:

effective area of detector

type: string

choose between auger_17, auger_19 and TA_19

Returns

——-

eventrate for an isotropic flux with given energy and zenith angle.

The differential flux is returned in d/d zenith_angle, not d/d solid_angle.

NuRadioReco.utilities.cr_flux.plot_measured_spectrum(ax=None, scale=2.7, type='data_auger_19', base_units=False)

Plot measured spectrum. Attention: time unit is year instead of ns.

Parameters:

ax:

axis on which the data is plotted

scale:

scale factor for energy, default = 2.7

type: string

choose between data_auger_19 and data_TA_21

base_units: bool

if False spectrum will be plotted in

[m^{-2} yr^{-1} sr^{-1} eV^{%scale-1}] instead of NuRadio base units

Returns:

plot of data without plt.show()
