Left: ratio of measured to true core mass as function of measured core mass for the simulated core extractions. The error bars are ±1σ where σ is the standard deviation of the mass ratio in each mass bin. The median mass ratio is ~ 0.75 for observed core masses between ~0.3 M_⊙ and ~ 0.8 M_⊙ (as indicated by the horizontal blue line). The horizontal dashed line indicates a mass ratio of 1, as expected for perfect core mass estimates. Right: difference between measured SED temperature and true mass-averaged dust temperature as function of measured core mass for the simulated core extractions. The error bars are ± 1σ where σ is the standard deviation of the temperature difference in each mass bin. The median temperature difference is approximately + 2 K between ~0.3 M_⊙ and ~ 0.8 M_⊙ (as marked by the horizontal blue line), close to the fiducial completeness limit. The horizontal dashed line indicates no temperaturedifference, as expected for perfect core temperature estimates.
