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 [8] 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)

beta_p()

template<typename realT , typename iosT = std::ostream>

virtual realT mx::AO::analysis::pywfsModAsymptotic< realT, iosT >::beta_p ( int  m, int  n, realT  D, realT  d, realT  r0  )

inlinevirtual

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)

inlinevirtual

Get the read noise sensitivity at a spatial frequency.

Here we assume beta_r is the same as beta_p
