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/casa/logging/LogIO.h>
cout << "TAI for UTC = MJD(50237.29): " <<
MEpoch::Convert(MEpoch(MVEpoch(Quantity(50237.29, "d")),
endl;
LogIO os(LogOrigin("FluxCalc_SS_JPL_Butler", "readEphem"));
os << LogIO::DEBUG1 << " at ";
os.output() << MEpoch::Convert(MEpoch(MVEpoch(Quantity(50237.29, "d")),

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)

Member Function Documentation

static const String* casacore::MEpoch::allMyTypes ( Int nall,
Int nextra,
const uInt *&  typ 
)
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.

Thrown Exceptions

  • AipsError if a (programming) error in the types.
