Equivalent width of Hα (plotted as ﹩{\mathrm{log}}_{10}(10-{W}({\rm{H}}\alpha )﹩) as a function of spectral type for Haro 5-2A and B, at each epoch for which we obtained low-resolution spectra at SOAR. Haro 5-2A is plotted as large purple boxes, and Haro 5-2B as large red boxes. For comparison, the Orion TTSs from Briceño et al. (2019) are also shown: CTTSs as red circles, and WTTSs as smaller blue dots. The separation between CTTS and WTTS as defined by White & Basri (2003) is shown with the black dashed line, while the criterion adopted by Barrado et al. (2011) is plotted as a dashed–dotted magenta line. The transition region adopted by Briceño et al. (2019) between CTTS and WTTS is shown by the pale green region where C/W objects fall (shown as green dots).
