Notes. The column “true values” refers to the MC input parameters,
except for Tin, γ, and
γ′ which are determined from the results of the MC simulation.
The columns “two power-law” and “one power-law” list the best-fit parameters
obtained with FRACS assuming two and one power-law for the temperature respectively.
The 
values
are respectively 0.73 and 0.79 for two and one power-law.
