! On the fly mode 
! Resol: big map 6'x 4' for SZ effect, at the limit possibilities
! in terms of speed
!
OTFMAP -180 -120 180 -120 - ! offsets at start and end of first otf subscan
  /system truehorizon - ! projection AzEl is used to define the map
  /zigzag - ! go back and forth
  /step 0 6 - ! steps between subscans in arcsecond (= 1.7 samples / HPBW_convol 1mm)
  /notf 41 - ! number of subscans
  /totf 20 - ! time of a subscan (18"/s)
  /reference no ! no off-source reference subscan

SAY "OTFMAP 360''x 240'' (step 6) in 41 subscans x 20 s = 14+3 ~= 17 min."
