!! /CROLOOP ROR means that there will be an
!! off-source reference subscan (R)
!! before and after each OTF suscan (O).
!! Therefore with /NOTF 4 on-the-fly subscans the complete
!! subscan sequence will be:
!! R OTF#1 R R OTF#2 R R OTF#3 R R OTF#4 R
!! with
!! /CROLOOP ROOROOR it would be:
!! R OTF#1 OTF#2 R OTF#3 OTF#4 R
