An energy diagram of H₂ at 2.25 arcsec to the northeast of the central region. Squares show the measured line intensities and the lines show expected H₂ line intensities for a given temperature. The slopes of the lines indicate the temperature of the H₂ and shows the modelled energy distributions for 1000 K, 1800 K, and 2400 K, where the vertical scales are arbitrary. The H₂ excitation temperature is above 1800 K.
