Notes. log10(λL5100) is the bright-state spectrum continuum luminosity, |Δfλ| ∝ λβ is the best-fitting power law index to the difference spectrum, and Type is the type of changing-look behaviour, with off indicating disappearing broad emission lines, and on indicating appearing broad emission lines.
