From 056d116db845bc7162e148cb5a9849360d949f0d Mon Sep 17 00:00:00 2001 From: Aaron LI Date: Thu, 1 Nov 2018 11:51:45 +0800 Subject: clusters/halo: Support to check whether halo is genuine Add the 'is_genuine()' method to check whether the radio halo is genuine by comparing the flux density to the fiducial value. Two new configuration options (fiducial_freq and fiducial_factor) are added to specify the frequency and limit whether the radio halo is regarded as genuine. --- fg21sim/configs/config.spec | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'fg21sim/configs') diff --git a/fg21sim/configs/config.spec b/fg21sim/configs/config.spec index 0d7e7aa..fefb8b8 100644 --- a/fg21sim/configs/config.spec +++ b/fg21sim/configs/config.spec @@ -440,3 +440,10 @@ stream = option("stderr", "stdout", "", default="stderr") # the acceleration is turned off and only leaves energy loss mechanisms. # Unit: [Gyr] time_init = float(default=1.0, min=0) + + # The frequency and factor used to determine whether the radio halo is + # genuine, i.e., the flux density at ``fiducial_freq`` is at least + # ``fiducial_factor`` times the fiducial value. + # Unit: [MHz] + fiducial_freq = float(default=150.0) + fiducial_factor = float(default=3.0, min=1) -- cgit v1.2.2
