on Linux installations of CASA indicate that the "geodetic" directory of your CASA installation needs to be updated.

Up to and including CASA 4.3 on Linux it has been possible to update the data repository of a CASA installation (including for example the leap seconds table) by typing at the shell prompt

svn update

in the "data" directory. This scheme will be abolished in the future and does not work for CASA OSX distributions. The recommended procedure is to either type at the shell prompt

cd <CASA-distro>/data
rsync -avz rsync:// .

or (with CASA 4.3 or later) run the Perl script "update-data." This can be executed from within CASA by typing


If you are using CASA 4.6, there is a known issue with the !update-data command.

The data repository update via !update-data does not work in CASA 4.6. The repository can be updated via
cd "CASA-ROOT"/data rsync -avz rsync:// .
where "CASA-ROOT" is your installation directory of your CASA version.
