Left panels – IRS/SH maps of the H₂ 0−0 S(2) to H₂ 0−0 S(1) total flux ratio (top left panel), and the map of the estimated T_ex (K) of the molecular hydrogen. The peak excitation temperature of  ~528 K is reached about  ≳2.3′′ (one pixel) to the north of the H₂O mega maser. Right panels – Same as above, but using the extinction corrected fluxes of the H₂ S(2) and S(1) lines. The extinction correction leads to an  ~100 K lower peak temperature.
