Parameter constraints from fitting the time–resolved spectra at X2 and X3 with the slimdz model.

Notes. Same as Table D.3, but here we assume the best–fit black hole parameters (M_• = 5 × 10⁴, a_• = 0.99) derived from the early θ–varying scenario (Table D.2). Good fits to both X2 and X3 spectra can only be achieved by letting both ṁ and θ free to vary between the peaks and the valleys.
