Prerequisite

Measure class

Etymology

From Measure and uvw

Synopsis

Muvw is the derived Measure class for an interferometer uvw. uvws 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 uvw), plate motion (not relevant for telescopes on same plate) and relativistic effects are incorporated. B1950 has the same caveat as in MDirection.

Example

// Specify an Epoch and a telescope position
MEpoch tbm(Quantity(50927.92931, "d"));
MPosition pos(MVPosition(-4750915.84032, 2792906.17778, 
-3200483.75028), 
MPosition::ITRF);
// Use them in a frame
MeasFrame mf(tbm, pos);
// Specify an uvw (note that values here are in m)
MVuvw mvb0(100,10, 0);
cout << "uvw: " << mvb0 << endl;
// Specify a reference (type and where and when) for the following uvw
Muvw::Ref mbref0(Muvw::ITRF, mf);
Muvw mb0(mvb0, mbref0);
// Show the uvw
cout << "uvw: " << mb0 << endl;
cout << "uvw reference: " << mbref0 << endl;
// Another reference
Muvw::Ref mbref1(Muvw::J2000);
cout << "uvw reference: " << mbref1 << endl;
// Convert the uvw coordinates to the other reference and show it
cout << "Test uvw conversion..." << endl;
Muvw::Convert bconv(mb0, mbref1);
cout << "Converted " << mb0 << endl <<
" to " << mbref1 << endl <<
" as " << bconv() << endl;

Motivation

To be able to handle conversions between uvw coordinates with different reference directions.
