Integrated intensities of O2 are shown as contours for a range of model column densities as function of density (left) and temperature (right) for the 8.0 km s-1 component. The yellow solid line is the observed integrated intensity of the tentative detection and the shaded region represents the range of column densities for their corresponding temperatures. Left: Tkin = 30 K is assumed for different densities and right: n = 5 × 103 cm-3 is assumed for different temperatures.
