- classmethod VillarCoolingBlackbodySED.flux_log_cgs(nu: NumericalInput, t: NumericalInput, redshift: NumericalInput, luminosity_distance: NumericalInput, *, log_attenuation: NumericalInput | None = None, **parameters: CGSParameterValue) FloatResult#
Natural log of the observed flux density, taking and returning plain cgs numbers.
Unlike
flux_log(),redshift/luminosity_distanceare not resolved from a cosmology here – pass already-computed values directly (e.g. a precomputed per-event grid).- Parameters:
nu (
array-like) – Observed frequency (Hz) and time since explosion (s).t (
array-like) – Observed frequency (Hz) and time since explosion (s).redshift (
array-like) – Cosmological redshift, dimensionless.luminosity_distance (
array-like) – Luminosity distance, in cm.log_attenuation (
array-like, optional) – Natural log of an observed-frame multiplicative attenuation, added directly to the log flux. Must already broadcast against the natural output shape of this call.**parameters – This model’s parameter values, in cgs units.
- Returns:
The natural log of \(F_\nu\), in erg/s/cm^2/Hz. A scalar is returned if the result is 0-dimensional.
- Return type:
