Notes. The error bars on those parameters are calculated by propagating the uncertainties on the line fluxes, which include a 10% absolute flux calibration error and fitting errors added in quadrature. Rows describe each parameter for the nuclear, circumnuclear, and central regions. The parameters are the; (1) temperature of the cold component, (2) temperature of the hot component, (3) column density associated with the cold component, (4) column density associated with the hot component, (5) column density associated with the sum of the cold and hot component, (6) ortho-to-para ratio, and (7) total H2 mass.
