    <PerturbKind>Breathing</PerturbKind>
    Perturbation kind, one of Radial Vertical X Plus Breathing

    <PerturbIntens>0.15</PerturbIntens>
    Perturbation strength
    NB: if this factor is >>1 (absurd case) then the image looks strange
    as the perturbation 4-vel is ~ the Keplerian 4-vel, so
    the redshift distribution (hence the intensity)
    is more or less random.

    <OpticallyThick/>
    Always optically thick

    <RMax>50.</RMax>

    <SafetyValue> 50. </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.
