In its first form \onoff\ is used with \total.  Subscans are taken
alternating between a position that's considered to be ``ON-source''
and a reference position that's normally assumed to be ``OFF-source'',
i.e., free of emission.

The source signal is then calculated as the difference between
``ON'' and ``OFF''.

The basic parameters are 
the offsets for the ON position,
parameters of the options are the 
offsets for the reference position, 
the (total) number of subscans, and 
the time per subscan in [s].
