Uses deflection to compute and plot the gravitational bending of light by the Sun at the Earth as a function of angle to the star, based on the formulas of Cowling (1984). See also deflectionPlotJupiter, deflectionPlotSaturn, deflectionPlotUranus, and deflectionPlotNeptune which encode their masses and nominal distance/angular radius, and allow you to enter the exact current distance (AU) and angular radius.


          smallestBeamMilliarcsec=30, m=1.989e+33, 
          r=14959700000000.0, source='Sun',   
          maxAngleDegrees=180, limbRadiusArcsec=947.1835, 
          secondPointArcsec=-1, secondPointLabel='')


CASA <2>: tt.deflectionPlot()


CASA <3>: tt.deflectionPlotUranus(r=19.67, limbRadiusArcsec=3.588/2)
In this function, I have also indicated the angular radius of the 6 flanking fields of the 7-point hexagonal mosaic obtained as a test observation in ICT-4143.

CASA <4>: tt.deflectionPlotSaturn(r=9.8, limbRadiusArcsec=16.95/2)


CASA <5>: tt.deflectionPlotJupiter(r=6.38, limbRadiusArcsec=30.898/2)
