Last change on this file since 2768 was 2726, checked in by Kana Sugimoto, 12 years ago

New Development: No

JIRA Issue: Yes (CAS-4141)

Ready for Test: Yes

Interface Changes: Yes

What Interface Changed: moved various set methods in python to c++

Test Programs:

Put in Release Notes: No

Module(s): sbseparator

Description:

Moved set methods in sbseparator module to c++ (STSideBandSep class).
