Effect of different calibrations for the Sun using MESA. The solid line indicates the track for calibration performed using just the solar luminosity, temperature and Z/X. The dashed line additionally includes the depth of the solar convection zone. The dotted line includes all constraints including the rms sound speed. The red point represents the Sun. The upper panel shows tracks computed with the GS98 abundances, while the lower one shows tracks computed with the A09 abundances.
