Equivalent width of Hα as a function of the 10% width of the Hα line profile, for Haro 5-2A (large blue boxes) and Haro 5-2B (large red boxes), measured in the two epochs during which we obtained high-resolution spectra at SOAR. Data are also shown for the Orion TTS from Briceño et al. (2019): CTTSs as red dots, WTTSs as smaller cyan dots, and C/Ws as green diamonds. The separation between CTTSs and WTTSs as defined by White & Basri (2003) is shown with the vertical blue dashed line at 270 km s⁻¹.
