!! IMPORTANT NOTE: ONOFF with SWWOBBLER (wobbler switching on-off)
!! requires that the subscans are offset relative to the source
!! in the trueHorizon system by -1 * the Wobbler elongations (offsets).
!! With the commands above, paKo recognizes this and automatically
!! sets the correct values.
!! In this case, OFFSETS can be used to set additional mapping
!! offsets in the "projection" of the astronomical coordinate
!! system. These mapping offsets in the projection apply
!! to all ONOFF subscans.
