NOTE

All spectra shown in figures and archived on files at the CDS have been 
Hanning smoothed. Therefore, adjacent channels have correlated noise.
This should be taken into consideration when evaluating noise and errors
(this has been taken into account in the errors listed in the tables).

ERRATUM

Printed paper:

The correct url for the database website at Meudon is
http://wwwusr.obspm.fr/~crovisie/basecom/ instead of
http://www.usr.obspm.fr/~crovisie/basecom/

Online material at EDPS:

Commet 19P/Borrelly: the first sum spectrum in Fig. A.35a
is erroneous (the last individual spectrum is shown instead).
This has been corrected in the CDS data.

In some cases, the names of the comets which appear on the
figures of the Appendix correpond to provisional designations.
This has been corrected in the CDS data.
