Table of the notations.
Wavelength	$\lambda$
Central wavelength	$\lambda_0$
Bandwidth	$1/R_\lambda = \Delta\lambda/\lambda_0$
Star flux in the pupil upstream of the coronagraph	$\psi_0$
Pupil diameter in the image channel	D
Pupil diameter in the reference channel	$D_{{\rm R}}$
$D/D_{{\rm R}}$	$\gamma$
Flat pupil of diameter D (1 inside, 0 outside)	P
Pupil coordinate	$\xi$
Phase aberrations upstream the coronagraph	$\phi_\lambda(\xi)$
Amplitude aberrations upstream the coronagraph	$a(\xi)$
Pupil star amplitude in the image channel	$\psi_{{\rm S},\lambda}(\xi)$
Pupil star amplitude in the reference channel	$\psi_{{\rm R},\lambda}(\xi)$
Pupil separation	$\xi_0$
Focal plane angular coordinate	$\alpha$
Amplitude in the detector plane for $\lambda$	$A_{i,\lambda}(\alpha)$
Intensity in the detector plane for $\lambda$	$I_{i,\lambda}(\alpha)$
Polychromatic intensity in the detector plane	$I_{i}(\alpha)$
Number of actuators of the deformable mirror	$N_{\rm act}$ x $N_{\rm act}$
Interferential image in the detector plane	$I(\alpha)$
Estimation of $I_{{\rm R}}(\alpha)$	$\overline{I}_{{\rm R}}(\alpha)$
Estimation of $A_{{\rm R}}(\alpha)$	$\overline{A}_{{\rm R}}(\alpha)$

Index i represents ${\rm R}$ , ${\rm S}$ , or ${\rm C}$ referring to the reference channel, the stellar residue of the image channel and the companion light of the image channel.
