    <Mass unit="sunmass">4.31e6</Mass>
          This is the mass of SgrA*, in solar mass.

          The distance to SgrA*.
    <Time unit="yr"> 30e3 </Time>
    <FieldOfView unit="µas"> 150 </FieldOfView>
          A reasonable field-of-view, about 15 Schwarzschild radii.
    <Inclination unit="°"> 90 </Inclination>
          90° is edge-on

  <!--Quantities>BinSpectrum[W/m²/pix²]</Quantities-->
          This is what a real-life detector measures.
  <Quantities>Spectrum[mJy/pix²]</Quantities>
          This unit can easily be confronted to observations.

  <Astrobj kind = "PolishDoughnut" plugin = "stdplug">
          We can specify the plug-in in which this Astrobj is implemented.
    <Lambda>0.3</Lambda>
    <CentralDensity unit="g/cm³">1e-17</CentralDensity>
          g/cm³ is actually the same as kg/L, the default.

    <Beta>0.1</Beta>
    <OpticallyThin/>
    <RMax>25.</RMax>
    <!--<UseSpecificImpact/>-->
          Set UseSpecificImpact to use the specific implementation of
          the Impact() method instead of Standard::Impact().
    <SafetyValue> 0. </SafetyValue>
          Increase SafetyValue if you have trouble resolving the
          surface of the doughnut. Increasing SafetyValue also
          increases computation time. The default value is slightly
          more conservative.
    <!--SpectralOversampling> 1 </SpectralOversampling-->
          Number of subsamples to use when computing BinSpectrum.
          More subsamples is more accurate but slower.
  </Astrobj>

  Those two are numerical tuning parameters:
  <Delta> 1e0 </Delta>
          Default (initial) step for geodesic integration
  <MinimumTime> 0. </MinimumTime>
          No light-ray will be integrated further in the past.

  Do we want to use multi-threading?
