classmethod KilonovaCoolingBlackbodySED.flux_log(nu: Quantity, t: Quantity, *, redshift: PhysicalInput | None = None, luminosity_distance: Quantity | None = None, angular_diameter_distance: Quantity | None = None, proper_distance: Quantity | None = None, cosmology: FLRW | None = None, log_attenuation: NumericalInput | None = None, **parameters: ParameterValue) → FloatResult#

Natural log of the observed flux density, given physical-unit inputs.

Parameters:

  • nu (Quantity) – Observed frequency.

  • t (Quantity) – Observed time since explosion.

  • redshift (array-like or Quantity, optional) – Exactly one of redshift or the three distance keywords must be given; the rest are derived from it using cosmology (see resolve_cosmological_distances()). cosmology defaults to that function’s configured default.

  • luminosity_distance (Quantity, optional) – See redshift above.

  • angular_diameter_distance (Quantity, optional) – See redshift above.

  • proper_distance (Quantity, optional) – See redshift above.

  • cosmology (FLRW, optional) – See redshift above.

  • log_attenuation (array-like, optional) – See flux_log_cgs().

  • **parameters – This model’s parameter values. See eval_log_cgs().

Returns:

The natural log of \(F_\nu\), in erg/s/cm^2/Hz.

Return type:

numpy.ndarray or float
