2D distribution of the GP hyperparameters LengthScale_Time (vertical axis) vs. LengthScale_Wavelength (horizontal axis), showing how each transient class occupies distinct regions in this parameter space. TDEs (blue crosses) and SLSNe (pink diamonds) typically have moderate LengthScale_Time and LengthScale_Wavelength values, reflecting narrower spectral and temporal variations compared to SNe and AGNs. Contours denote the 50%, 80%, and 95% highest-density regions of the per-class 2D kernel density estimate.
