template<typename realT, typename iosT = std::ostream>
struct mx::AO::analysis::pywfsModAsymptotic< realT, iosT >
The asymptotic modulated pyramid wavefront sensor sensitivity function.
Provides the \( \beta_p \) parameter of Guyon, 2005 [9] for the modulated PyWFS in the asymptotic limit.
- Template Parameters
-
realT is the floating point type used for calculations iosT is an output stream type with operator << defined (default is std::ostream)

Get the photon sensitivity at a spatial frequency.
The photon noise sensitivity of the asymptotic modulated PyWFS is \( 2 \sqrt{2} \) at all k.
- Returns
- the sensitivity to photon noise parameter
- Parameters
-
[in] m the spatial frequency index for u (not used by this WFS) [in] n the spatial frequency index for v (not used by this WFS) [in] D the telescope diameter (not used by this WFS) [in] d the sub-ap spacing (not used by this WFS) [in] r0 Fried's parameter (not used by this WFS)
