This work was partially supported by the DFG grant Pf316/5-1. We acknowledge the excellent support of the ADONIS team during the adaptive optics observations, especially by P. Bouchet. We are indebted to M. Buchner for sacrificing observing time to contribute the NIR narrow-band data. M. Feldt is indebted to R. Klein and V. Manske for support with the radiative transfer software which was used to compute the model. We thank P.M. Harvey for letting us share their CO data of G5.89 as well as D.O.S. Wood for supplying the VLA data in FITS format. We acknowledge the service of the Canadian Astronomy Data Centre, which made IRAS LRS data available through http://cadcwww.dao.nrc.ca/astrocat/iras_lrs.html . We thank our referee John Mathis for valuable comments which helped to improve the paper.
