## Description

    This component works as other absorption loggers, but converts the tof and
    position data to wavelength, which is then compared to the actual wavelength
    calculated from the neutron state. The neutron position used to calculate
    the wavelength is pixelated while the time of flight is continous. The
    distance from source to sample is an input parameter, and the distance from
    sample to a detector pixel is calculated using the reference component position
    which should be specified with a relative component index. This test checks
    both the standard view with measured and true wavelength on each axis, and the
    relative where they have been normalized and a value of 1 is expected.
