OTFMAP -70 -45 70 -45 - ! 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 5 - ! steps between subscans in arcsecond (= 1 sample / HPBW_convol 1mm)
  /notf 19 - ! number of subscans
  /totf 14 - ! time of a subscan (10"/s) might have tracking errors
  /reference no ! no off-source reference subscan

SAY "OTFMAP 140''x 90'' in 19 subscan x 14 s = 4+1 ~= 5 min."
