To first order, using the new protocol to query the CDMS database
should be transparent to the end user. This is one of the purpose of
LINEDB. However, it seems that the database behind the new protocol
is not same as before. The user should be aware that:
- as of today, the request takes more time and more bandwidth than
before (48 minutes to download the database in the range 100-400
MHz, 893 MB in return),
- the species name/formula may be different between the old and
new database (e.g. ``Methanol'' vs ``CH3OH'', ``CCH, v=0'' vs
``CCH''),
- the vibrational state has been removed from the formulas (see
e.g. ``CCH'' above),
- querying a formula may return the same molecule under different
formulas (e.g. you ask for ``HCCCN'' and LINEDB returns ``HCCCN''
and ``HC3N''),
- some lines seem to have disappeared in the new database
