Excluding antennae from miriad data reductioin

Post by har866 »

Miriad falls over whenever I try to exclude an antenna or combination eg -ant(6) or ant(1,2,3,4,5)(1,2,3,4,5). Whichever combination I use, I get: "Badly placed () ." If I use no brackets, the task dies too.
Any ideas?

You must be trying to use miriad from the command line rather than the miriad shell.
On the command line you can either 'escape' brackets with \ or place the whole keyword=value in quotes:
% uvplt vis=data.uv "select=-ant(6)"

Cheers,

Hi Jules,

Can you give an example please? Are you trying to do this on the command line, or from within the Miriad shell?

If you're doing it on the command line, you need to put quotes around the select command. For example you could do something like:

Code: Select all

uvplt vis=dataset.uv "select=-ant(6)"
cheers
