ess.reflectometry.supermirror.supermirror_reflectivity(q, c, m, alpha)

Returns the reflectivity of the supermirror. For q outside of the region of known reflectivity this function returns nan.

Parameters:

• q (Variable) – Momentum transfer.

• m_value – m-value for the supermirror.

• critical_edge – Supermirror critical edge.

• alpha (supermirror.types.Alpha (scipp.Variable)) – Supermirror alpha value.

Returns:

Variable – Reflectivity of the supermirror at q.
