Abstract Since the apparition of comet Kohoutek 1973 XII, the 18-cm lines of the OH radical have been systematically observed in a number of comets with the Nançay radio telescope. Between 1973 and 1999, 52 comets have been successfully detected. This allowed an evaluation of the cometary water production rates and their evolution with time, as well as a study of several physical processes such as the excitation mechanisms of the OH radio lines, the expansion of cometary atmospheres, their anisotropy in relation to non-gravitational forces, and the Zeeman effect in relation to the cometary magnetic field. Part of these observations and their analysis have already been published. The bulk of the results are now organized in a data base. The present paper is a general presentation of the Nançay cometary data base and a more specific description of the observations of 53 cometary apparitions between 1982 and 1999. Comets observed before 1982 are only partly incorporated in the data base. Observations of comets since 2000 have benefited from a major upgrade of the telescope; they will be presented in forthcoming publications.

Electronic material

The 83 tables and 569 figures of the Appendix of the paper are only published electronically. They will be available from the CDS. They can also be accessed independently from below.

Tables are in plain ASCII. The format of the tables is explained in this file.

Figures are in both JPEG format for viewing, and postscript format (gzipped) for high-quality printing.

August 2002. The electronic material is undergoing minor modifications to comply with A&A requirements.
  • The Appendix of the paper will only be published electronically, available at EDPS.
  • The figures of the sum spectra only will be published electronically, available at EDPS.
  • All the spectra (individual and sum) will be available as FITS files at the CDS.
  • All the tables of the Appendix will be availaible at the CDS.
  • In the mean time, all the tables and the figures of all the spectra (sum and individual) are available from the present web page.

    October 2002. The paper (printed version and online material at EDPS) is now published. The material for CDS is being prepared.
