Figure 3.11 – Sample of continuum subtracted, normalized profiles of the Hα emission lines overplotted
with a Gaussian fit (light gray solid line) and a Voigt fit (dark gray solid line). The red
dotted line marks the center of the Gaussian fit.
Figure 3.12 – Histogram of the mass accretion rates derived from the Hα[10%] value. The shaded
area are objects out of the range for which the relationship of Natta et al. (2004) was calibrated.
Those objects are generally classified as non-accreters.
