Erratum to: Phase space of partially coherent light with discontinuous surfaces

Erratum

After publication of this work [1], it was noted that there was an error within equation 3. The correct version of equation 3 is found below:

$$ \Gamma \hbox{'}\left({\mathrm{x}}_1,\ {\mathrm{x}}_2\right)=\Gamma \left({\mathrm{x}}_1,{\mathrm{x}}_2\right)\cdot \mathrm{t}\left({\mathrm{x}}_1\right)\cdot {\mathrm{t}}^{*}\left({\mathrm{x}}_2\right)\ \mathrm{or} = \Gamma \left({\mathrm{x}}_1,{\mathrm{x}}_2\right)\cdot \mathrm{A}\left({\mathrm{x}}_1\right)\cdot {\mathrm{A}}^{*}\left({\mathrm{x}}_2\right) $$

We would like to apologise for the error and for any inconvenience this may have caused.
