Combined tracking confidence level (FOM) must be >= 0.001
Combined PID confidence level (FOM) must be >= 0.001
VERY loose cuts around invariant/missing mass peaks (keep enough data around peak to do sideband subtraction if desired)

Note: "MM" is short for missing mass, "MMS" for missing mass squared, and "IM" for invariant mass

Channel	Topology	Mass Peak Cuts
2π	γp→π⁺π^-p	-0.02 < MMS < 0.02
3π	γp→π⁺π^-π⁺(n)	0.3 < MM < 1.6
ωππ	γp→ωπ⁺π^-(p), ω→π⁺π^-π⁰, π⁰→γγ
