Last change on this file since 2962 was 2754, checked in by Takeshi Nakazato, 12 years ago

New Development: No

JIRA Issue: Yes CSV-2532 (may be related to CSV-1908 and CSV-2161)

Ready for Test: Yes

Interface Changes: Yes

What Interface Changed: In tool level, added parameter 'freq_tolsr' to

scantable constructor and function sd.splitant.

Test Programs: test_sdsave, test_importasdm_sd

Put in Release Notes: Yes

Module(s): Module Names change impacts.

Description: Describe your changes here...

In importing MS to Scantable, frequency frame information is
imported as is by default, i.e., base frame in Scantable is
TOPO for ALMA data, which is forcibly converted to LSRK with
wrong time and direction reference.

Some functions have a boolean parameter 'freq_tolsr' that controls
the above behavior. If freq_tolsr is False (default), frequency
is imported as is, while frequency is converted to LSRK (wrongly)
when it is True.
