Mass estimates
Notes (N):
1: This estimate is discarded for the average mass (and derived density) calculation in Carry (2012).
2: This estimate is discarded for the average mass (and derived density) calculation in SiMDA (catalog).
3: This estimate is an average of individual solutions listed before under the same reference (e.g. M125).
PheMu : Mutual eclipsing phenomena in binary systems.

EVM mass average M = (3.600 ± 1.800) × 10^{11} kg (ΔM/M = 50%, SNR = 2.0)
Derived bulk density ρ = (2.15 ± 1.56) g/cm^{3} (Δρ/ρ = 73%, SNR = 1.4)
