## Description

    A square single monitor that measures the projection of the
    polarisation along a given normalized m-vector (mx, my, mz) as a
    function of wavelength.

    Example: Pollambda_monitor(Lmin=1, Lmax=20, nL=20, xwidth=0.1, yheight=0.1, npol=11, mx=0, my=1, mz=0, filename="pollambdaMon.data")

## Input parameters

Parameters in boldface are required; the others are optional.
