Accretion disk characteristics. Quasi-stationary extent of disk (contours, radius in 10¹¹ cm, panel a) and radial velocity in orbital plane (in BH co-orbiting frame, radius in 10¹⁰ cm, panel b), inferred elliptical orbits (for one time and five color-coded pericenter distances log10(r), panel c), eccentricity and pericenter angle vs. semimajor axis (panel d), density and temperature profiles (for one time, ϕ = 180°), and three radii (in 10¹⁰ cm, colors), from data (solid and dashed) and via scaling law (dotted, panel e), disk thickness H_T/r and scale height H_S/r (panel f). The dashed lines (panel a) or shading (panels d and f) indicate the 25th to 75th percentile with respect to time. The circles in panel e indicate the 1° rays.
