This Atlas would not have been possible without the kindness of the observers who have sent us images and calibrated data. They are listed here.

Telescopes

MERLIN
The Multi-Element Radio Linked Interferometer Network. Operated by the University of Manchester on behalf of the Particle Physics and Astrophysics Research Council (PPARC).

VLA
The Very Large Array, operated by the National Radio Astronomy Observatory (NRAO), which is a facility of the National Science Foundation (NSF), operated under cooperative agreement by Associated Universities, Inc. (AUI).

N.B. in the "telescope" field of the main pages we list the VLA configurations used; e.g. VLA A+B means a combination of data from the A and B configurations.

WSRT
The Westerbork Synthesis Radio Telescope, of the Netherlands Foundation for Research in Astronomy (NFRA), a national facility supported by the Netherlands Organization for Scientific Research (NWO).

Other Acknowledgements

We thank Mike Evans, who, as a summer student in 1991, made many of the C20 images and took a lot of the morphological measurements. He also compiled most of the data from the literature, and created the prototype of this Atlas, as a hypercard stack. The web version of the Atlas was inspired by the SEDS Messier Database, (well worth checking out), created by Guy McArthur and Hartmut Frommert. For their M.Sc. technical projects, Jolene Horlock and Paul Rayner produced the prototype search page and frames/Java navigation bar, respectively.
