Weeds used to rely on a Python library,
linedb, for querying
spectral line databases. This library has been developed as part of
Weeds, but it has been realized that it could be useful in other
GILDAS programs as well. Therefore it has been moved to the GILDAS
kernel, after some important modifications to make it more generic and
versatile. It is now a separate language (see
help linedb\ for
more information). As a consequence, a couple of Weeds commands have
dbselecthas been removed. The database selection is now made with the
use incommand, which is part of the
dbcachecommand has also been removed. Users can now build a local copy of a database with a combination of
insert. See section 3 for an example of this.
In addition, the following changes have been implemented in this release:
modsourcenow allows to model sources with one or several foreground absorbing layers. This is set with the
/absorptionoption in the model file. See the
modsourcecommand help for more information.
modsourcehas been corrected. The interpolation is now done in log-log.
lidnow prints the uncertainty on the line frequencies
