Example 4

ONOFF observations with WOBBLER SWITCHING are a special case, because the offsets for the subscans must be in system trueHorizon and their values must be selected according to the offsets of the WOBBLER SWITCHING! E. g.,

SWWOBBLER -33 +33
ONOFF 33 0 /REFERENCE -33 0 trueHorizon /SYSTEM trueHorizon

This can also be achieved simply by saying

SWWOBBLER -33
ONOFF

PAKO ``knows'' the special requirements for onoff wobbler switching, and will set the offset parameters for ONOFF accordingly, if SWWOBBLER has been previously selected. 7

In this special case, in order to map the source, the observer may add offsets on the source $l$ and $b$ using the command OFFSETS with the system ``projection'', e.g.:

SWWOBBLER -33
OFFSETS 110 120 /SYSTEM projection
ONOFF
