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
been modified:
dbselect
has been removed. The database selection
is now made with the use in
command, which is part of the
linedb\
language.
dbcache
command has also been removed. Users can
now build a local copy of a database with a combination of
use in
, use out
, select
and
insert
. See section 3 for an
example of this.
In addition, the following changes have been implemented in this release:
modsource
now allows to model sources with one or
several foreground absorbing layers. This is set with the
/absorption
option in the model file. See the
modsource
command help for more information.
modsource
has been
corrected. The interpolation is now done in log-log.
lid
now prints the uncertainty on the line frequencies
