        the step wedge patches will be used in making the profile,
but there will be no calibration/linearisation curves. Calibration
really should be applied in series with profiling, so means calibrating
as a separate step.

Yes. This is the most accurate and effective way of doing it. I haven't
attempted to create tools that will fudge calibration and profiling in
one step, since this compromises the result (dispcal being the only
exception, and the resulting profile is quick and simple rather than

For 4 or less channels, it is better to use the default (ie. not -t).
