that's telling you that the image you are loading has secondary
extensions with additional information. The top line is simply the
cube you thought you were loading. The next few lines are additional
images created by makecube. They are the exposure time, effective
exposure time and Tsys images. The window will popup each time.

CLASS looks like it still can't handle binary extensions (we create
exposure time and tsys images from makecube in extensions ) so I think
you need to disable the propagation of extensions with PROEXT=NO.
