Yes, at time only Quickbird but not GeoEye-1 and Worldview-3 are supported.

We would be happy to add support for these sensors. We need the
spectral filter curves for that, in order to integrate them in

The procedure is explained here:

I can do this integration but I would need to get the filter curves of
GeoEye-1 and Worldview-3 for that (no time to search myself).
