Notes. For SRGe J235453.0+421711 (ID 70), the skewness of He II λ4686 line is −0.36 ± 0.29. Given the non-detection of Hα, we classify this object as TDE-He. While a Gaussian centered on Hβ is favored by BIC (ΔBIC = 11.42 > 10), we note that this line detection is of very low significance (2.6σ). Similarly, given the low significance of line EWs of SRGe J153331.5+390536 (ID 39), we do not assign a spectroscopic subtype for this event.
