Message:

New Development: No

JIRA Issue: No (Bug fixes)

Ready for Test: Yes

Interface Changes: Yes

What Interface Changed: Added a function Scantable::nValidMask(const std::vector<bool>& mask);

Test Programs:

Put in Release Notes: Yes

Module(s): scantable, sdbaseline

Description:

• Added a new function Scantable::nValidMask(const std::vector<bool>& mask) that returns the number of elements in true in the input bool vector, mask.
• Fixed a bug in Scantable::isAllChannelsFlagged that fails to detect completely flagged channels when BDF flag and the other flag is mixed in a spectrum.
• Fixed a bug in *Baseline functions that caused an error of baseline subtraction in case there is a spectrum of which all channels are flagged.

• Scantable.cpp (modified) (10 diffs)
• Scantable.h (modified) (1 diff)
