Plotting

To plot Stokes values, the plotter set_cursor function should be called first using the pol argument. The values which can be plotted include a selection of [I,Q,U,V], [I, Plinear, Pangle, V], [RR, LL] or [XX, YY, Real(XY), Imaginary(XY)]. (Plinear and Pangle are the percentage and position angle of linear polarisation). Conversion to circular polarisations are currently not available.

Example:

  ASAP> plotter.set_cursor(pol=``I Q'')
  ASAP> plotter.set_cursor(pol=``RR LL'')
  ASAP> plotter.set_cursor(pol=``XX YY'')
  ASAP> plotter.set_cursor(pol=``I Plinear'')

Row, beam and IF selection are also available in set_cursor as describe in section 9.1.
