Etymology

Synopsis

MEpoch forms derived Measure class for an instant in time.

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>
#include <casacore/casa/logging/LogIO.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;
LogIO os(LogOrigin("FluxCalc_SS_JPL_Butler", "readEphem"));
os << LogIO::DEBUG1 << " at ";
os.output() << MEpoch::Convert(MEpoch(MVEpoch(Quantity(50237.29, "d")),
MEpoch::Ref(MEpoch::UTC)),
MEpoch::Ref(MEpoch::TAI))();
os << LogIO::POST;

Results in:

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

at Epoch: 50237::06:58:06.0000 (in logger)

casacore::MEpoch::MEpoch ( )

Tip: In the following constructors and other functions, all MeasRef can be replaced with simple Measure::TYPE where no offsets or frames are needed in the reference;
Default constructor; generates an instant at MJD 0 UTC

casacore::MEpoch::MEpoch ( const MVEpoch & dt )

Create from data and reference.

casacore::MEpoch::MEpoch	(	const MVEpoch &	dt,
		const MEpoch::Ref &	rf
	)

casacore::MEpoch::MEpoch	(	const MVEpoch &	dt,
		MEpoch::Types	rf
	)

static

virtual const String* casacore::MEpoch::allTypes	(	Int &	nall,
		Int &	nextra,
		const uInt *&	typ
	)		const

virtual

Get a list of all known reference codes.

nall returns the number in list, nextra the number of specials (like planets) that should be at end of list). typ returns the list of corresponding types.

Reimplemented from casacore::Measure.

static void casacore::MEpoch::assure ( const Measure & in )

static

static MEpoch::Types casacore::MEpoch::castType ( uInt tp )

static

Translate reference code.

The uInt version has a check for valid codes (i.e. it is a safe cast).

Thrown Exceptions

AipsError in the uInt interface if illegal code given

static void casacore::MEpoch::checkMyTypes ( )

static

virtual void casacore::MEpoch::checkTypes ( ) const

virtual

Check if all internal tables of types (both enum and String) are complete and correct.

This function is called automatically if and when necessary.

virtual

Tell me your type.

Implements casacore::Measure.

virtual uInt casacore::MEpoch::type ( ) const

virtual

Get the type (== Register() of derived Measure (faster than Strings) All should have: static uInt myType();.
