casa warning - out of date

[TariqBlecher]

Any idea as to how serious this is?

I think it is quite serious, as I got empty images from measurement sets which produced this error while being simulated. I entered a date in the 1990s and it worked fine.

That's odd, I often ignore this error and there's no problem. In theory all it means is that the coordinate calculations can be very slightly off. Updating the casa data tables to the latest should fix it, anyway.

I'm a little late to this party, but in case you didn't know, just run the command $CASAROOT/lib/casa/bin/update-data
where-ever your CASAROOT is.
