Appendix A: The database

The database is composed of:

1.: Optical spectra of 35 galaxies taken with Boller & Chivens Cassegrain spectrograph at the ESO 1.52 m telescope (La Silla). The spectra shown are in restframe wavelength versus Flux, which was normalized to 10 flux units at 5870 Å.
2.: ¹²CO(1-0) spectra of 47 galaxies, and ¹²CO (2-1) spectra of 14 galaxies taken with the SEST telescope. The spectra shown are in heliocentric velocities (km s^-1) versus main beam Temperature ( $T_{\rm mb}$ ) in mK. Spectra were binned with a boxcar function resulting in a velocity resolution of $\sim$ 20-30 km s^-1. Spectra were corrected for first or, in a few cases, third order baseline.
3.: We have also included images from The Digitized Sky Surveys which allows direct inspection of the morphology of the galaxies. All images are of size 8 $' \times$ 8' and centered on the objects. North is to the top and East is to the left. The designation in the ESO-Uppsala catalog (Lauberts & Valentijn 1989) and the type of sample (control sample=CS and high density sample=HDS) are given below each image.
