Prerequisite

Etymology

From Measure and Baseline

Synopsis

MBaseline forms derived Measure class for an interferometer baseline. Baselines can be given in any of the direction types, or as ITRF, the IERS base.
Note that at the moment no correction for Earth tides (error <~ 0.05 mm/km EW baseline), plate motion (not relevant for telescopes on same plate) and relativistic effects are incorporated. B1950 has the same caveat as in MDirection .

Example

Motivation

To Do

add some Earth tide model

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 the ITRF centre

casacore::MBaseline::MBaseline ( const MVBaseline & dt )

Create from data and reference.

casacore::MBaseline::MBaseline	(	const MVBaseline &	dt,
		const MBaseline::Ref &	rf
	)

casacore::MBaseline::MBaseline	(	const MVBaseline &	dt,

virtual const String* casacore::MBaseline::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::MBaseline::assure ( const Measure & in ) [static]

static MBaseline::Types casacore::MBaseline::castType ( uInt tp ) [static]

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
