+|If the 2-norm of an interaction tensor is below this threshold (in rad/s), the interaction is ignored. The same threshold applies to bosonic mode couplings declared in [[Spin system specification#Bosonic modes|inter.modes]]; dropped mode couplings are reported to the console by channel and particle pair.
