/SYMMETRIC [yes|no]

Logical   :: doSymmetric      ! default: no

(For ONOFF) select a subscan sequence that is "symmetric" in time.
This requires that the number of subscans is a multiple of 4.

Example for ONOFF with /SYMMETRIC no     /SYMMETRIC yes
1st subscan:                      OFF               OFF          
2nd  "                            ON                ON
3rd  "                            OFF               ON
4th  "                            ON                OFF
(and so on)

NOTE that this does not in anyway change the positions
of the ON-source and OFF-source subscans!
