 <h3>Review Status</h3><dl><dt>Reviewed By:<dd>UNKNOWN<dt>Date Reviewed:<dd>before2004/08/25<dt>Test programs:<dd>tMuvw</dl> 

Prerequisite

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.

Member Function Documentation

static const String* casa::Muvw::allMyTypes ( Int nall,
Int nextra,
const uInt *&  typ 
) [static]
virtual const String* casa::Muvw::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 casa::Measure.

static void casa::Muvw::assure ( const Measure in) [static]
static Muvw::Types casa::Muvw::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 casa::Muvw::checkMyTypes ( ) [static]
virtual void casa::Muvw::checkTypes ( ) const [virtual]

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