Ages and masses determined by the SCEPtER pipeline.
Top row: left Monte Carlo relative errors on mass estimate as a function of the true mass of the stars. The black lines show the position of the median (dashed line) and the 1σ envelope (solid line). The red lines show the corresponding quantities, but for weighted estimates. Right: same as in the left panel, but as a function of the relative age of the stars. Bottom row: same as the top row, but for age estimates.
