Etymology

Measure, Convert and Doppler

Synopsis

Contains state machinery and caching for actual conversions

Example

Conversion of a radio Doppler to an optical

#include <casacore/measures/Measures.h>
#include <casacore/measures/Measures/MDoppler.h>
MDoppler radio(0.01);      // A radio Doppler value
cout << "Doppler radio = " << radio << "; optical = " <<
MDoppler::Convert(radio, MDoppler::OPTICAL)() << // Convert 
endl;

Setting up a conversion

MDoppler::Convert to_opt(MDoppler::RADIO, MDoppler::OPTICAL);
for (Double d=0; d<0.1; d += 0.005) {
cout << "radio = " << d << " to optical = " <<
to_opt(d) << endl;

The list of actual routines provided.

Warning: Each AA_BB in the list points to routine that can be used in the FromTo list in the getConvert routine; In addition the type to which each is converted should be in the ToRef array, again in the proper order;
