Synopsis

Contains state machinery and cashing for actual conversions

Example

Get the Doppler shift for an oberved HI RadialVelocity of 100 km/s

#include <casacore/measures/Measures.h>
#include <casacore/measures/Measures/MRadialVelocity.h>
#include <casacore/measures/Measures/MDoppler.h>
cout << "Redshift for 100 km/s: " <<
MDoppler::Convert(MRadialVelocity(Quantity(100., "km/s"),
MRadialVelocity::TOPO).toDoppler(QC::HI),
MDoppler::Z)() << endl;
