Table 2: Intensity of the CO(2-1) emission lines in the Shields and Filippenko star cluster region. Two Gaussians have been fitted. Around half of the total area is found in a broad line (300 km s^-1) and the other half is found in a narrower (130 km s^-1) component. The stronger emission could be associated with the star cluster and the smaller one with the underlying filament.
