Etymology

Measure, Convert and Epoch

Synopsis

Contains state machinery and caching for actual conversions

Example

Convert (with all steps explicit) a UTC to an IAT time.

#include <casacore/measures/Measures.h>
#include <casacore/measures/Measures/MEpoch.h>
#include <casacore/measures/Measures/MCEpoch.h>
cout << "TAI for UTC = MJD(50237.29): " <<
MEpoch::Convert(MEpoch(MVEpoch(Quantity(50237.29, "d")),
MEpoch::Ref(MEpoch::UTC)),
MEpoch::Ref(MEpoch::TAI))() <<
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;
