Comparison between the virial masses and gas masses of the resolved cores in IRAS 19410+2336. Virial masses are unaffected by the interferometric flux filtering, which do affect the gas masses. The red dots are the actual values obtained, while the blue crosses represent the relationship if we take into account ~10% of the flux filtered out by the interferometer. This is a hint of the care that must be taken when interpreting interferometric flux values.
