Mean magnitude offset between our magnitudes and those by M09 and M13 (⟨K_s⟩(M09, M13)). Blue circles display T2Cs, red circles display CCs, and gray circles display Miras. The black solid line represents the average, and the black short-dashed lines the standard deviation of the whole sample. The black, thick, solid, and long-dashed lines have the same meaning for saturated (⟨K_s⟩< 12 mag) and nonsaturated (⟨K_s⟩> 12 mag) targets in the VVV.
