\caption{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.
