Bases: BaseParameters

Class to store stellar flare parameters

Parameters:

  • dist_teff_mean (astropy.units.Quantity) – The mean of the temperature distribution.

  • dist_teff_sigma (astropy.units.Quantity) – The standard deviation of the temperature distribution.

  • dist_fwhm_mean (astropy.units.Quantity) – The mean of the FWHM distribution.

  • dist_fwhm_logsigma (float) – The standard deviation of the logorithm of the FWHM distribution in dex.

  • alpha (float) – The slope of the log frequency - log energy relationship.

  • beta (float) – The y-intercept of the log frequency - log energy relationship.

  • min_energy (astropy.units.Quantity) – The minimum energy to consider. Set to np.inf*u.erg to disable flares.

  • cluster_size (int) – The typical size of flare clusters.
