Last change on this file since 1686 was 1684, checked in by Takeshi Nakazato, 15 years ago

New Development: No

JIRA Issue: Yes CAS-1810

Ready to Release: Yes

Interface Changes: Yes

What Interface Changed: Added 'antenna' parameter to scantable constructor

Test Programs: List test programs

Put in Release Notes: Yes

Module(s): atnf

Description: Describe your changes here...

I have added 'antenna' parameter to scantable constructor to be able to
select specific antenna from MS data with multiple antenna data.
Currently, only single antenna selection is working. For multiple antenna
selection, only first selection is used.
