If you > select all then you get 1..28 inclusive. I can do this but it's not entirely clear that it's a good idea since it will add some overhead. There are two options: (1) Just read the ANTENNAs listed in the MS and return only those. Cheapish and fast. (2) Actually look for valid data. Slow and expensive. > > 2) Clicking on antennas is fine.

Agreed (and expected!). > > 3) It isn't real clear to me how to actually get this tool to feed > the antennas you select into the calibrater tool. It should be > integrated into the setdata command.
