Message:

New Development: No

JIRA Issue: Yes (CAS-1079)

Ready to Release: Yes

Interface Changes: Yes

What Interface Changed:
Added the new functions to get min/max position (channel) of spectra.

1. std::vector<int> asap::python::stmath::_minmaxpos(ScantableWrapper?& in,

std::vector<bool>& mask, std::string& which)

@python_STMath.cpp

2. std::vector<int> STMathWrapper::minMaxPos(ScantableWrapper?& in,

std::vector<bool>& mask, std::string& which)

@STMathWrapper.h

3. std::vector<int> STMath::minMaxPos(CountedPtr?< Scantable > & in,

std::vector< bool > & mask, std::string& which)

@STMath.h & .cpp

4. IPosition mathutil::minMaxPos(String& which, MaskedArray?<Float>& data) @MathUtils?.h & .cpp

Test Programs:

Run scantable.stats() with the parameter stat='minpos' or 'maxpos',
and you'll get min/max value with its psition.

Put in Release Notes: No

Module(s): scantable.stats()

Description:

These modifications are to return min/max value with its
position (channel/frequency/velocity) by running scantable.stats().

Diagram:
scantable.stats() ->asap::python::stmath::_minmaxpos
-> STMathWrapper::minMaxPos -> STMath::minMaxPos() -> mathutil::minMaxPos()
-> casa::minMax (@casacore/casa/casa/Arrays/MaskArrMath.tcc)
