    left-hand-edge, with no wraparound effects.  
 
    This works together also with the 'm_map' option.  In this case LONO 
    should be between -180 and 180, and one must set the maximum longitude
    in M_MAP to LONO. For a global plot, this means one will call M_PROJ as
  
          M_PROJ(...,'longitudes',[LONO-360 LONO],...).
 
    If you run <a href="cellplot.html">CELLPLOT</a> with M_MAP and data doesn't show up, make sure 
    the longitudes have been set correctly.
