Some public strips have been removed on 1999 March 19:
The DENIS data which were released on 1998 Dec. 21 are not
part of the final DENIS catalogue. They were only made
available to the public as a first test sample. The pipeline
used for sources extraction has undergone several changes
since, leading to major improvements in the data quality.
Some of the data
(19 strips) were suppressed on 1999 Mar. 19,
because their quality was found not to be sufficient.
These problems should disappear in the next release of the
DENIS data: artifact filtering will be more efficient, and the
final astrometry will be based on the Tycho catalogue (via
the USNO A2.0 catalogue).
is now given on each strip, and users are
encouraged to refer to these pages for additional information
on the quality of the data they retrieve.
