Etymology

Measure and Epoch

Synopsis

MEpoch forms derived Measure class for an instant in time.

Example

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

        #include <measures/Measures.h>
        #include <measures/Measures/MEpoch.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;

Results in:

        TAI for UTC = MJD(50237.29): Epoch: 50237::06:58:06.0000

Member Enumeration Documentation

enum casa::MEpoch::Types

Types of known MEpochs Caution: The order defines the order in the translation matrix in the MCEpoch class.

Do not change the order without changing the array. Additions should be made before N_types, and an additional row and column should be coded in FromTo (MCEpoch), and in showType().

Reimplemented from casa::Measure.
