redback.transient_models.combined_models.tophat_and_twolayerstratified(time, redshift, av, thv, loge0, thc, logn0, p, logepse, logepsb, ksin, g0, mej, vej_1, vej_2, kappa, beta, **kwargs)[source]

function to combine the flux density signals of a tophat afterglow and a two layer stratified kilonova with extinction

Parameters:

  • time – time in days in observer frame

  • redshift – source redshift

  • av – absolute mag extinction

  • thv – viewing angle in radians

  • loge0 – log10 on axis isotropic equivalent energy

  • thc – half width of jet core/jet opening angle in radians

  • beta – index for power-law structure, theta^-b

  • logn0 – log10 number density of ISM in cm^-3

  • p – electron distribution power law index. Must be greater than 2.

  • logepse – log10 fraction of thermal energy in electrons

  • logepsb – log10 fraction of thermal energy in magnetic field

  • ksin – fraction of electrons that get accelerated

  • g0 – initial lorentz factor

  • mej – ejecta mass in solar masses

  • vej_1 – velocity of inner shell in c

  • vej_2 – velocity of outer shell in c

  • kappa – constant gray opacity

  • beta – power law index of density profile

  • kwargs – Additional keyword arguments

  • r_v – extinction parameter, defaults to 3.1

  • spread – whether jet can spread, defaults to False

  • latres – latitudinal resolution for structured jets, defaults to 2

  • tres – time resolution of shock evolution, defaults to 100

  • spectype – whether to have inverse compton, defaults to 0, i.e., no inverse compton. Change to 1 for including inverse compton emission.

  • q (l0, ts,) – energy injection parameters, defaults to 0

  • frequency – frequency to calculate - Must be same length as time array or a single number

Returns:

flux density signal with extinction added
