Synopsis

Contains state machinery and caching for actual conversions

Example

Get the Doppler shift for an oberved HI frequency of 1380 MHz

#include <casacore/measures/Measures.h>
#include <casacore/measures/Measures/MDoppler.h>
#include <casacore/measures/Measures/MFrequency.h>
cout << "Redshift for 1380 MHz: " <<
MDoppler::Convert(MFrequency(Quantity(1380., "MHz"),
MDoppler::Z)() << endl;
MeasConvert< MDoppler > Convert
