docs: NAME:
  
             _nemo_accpars
  
          PURPOSE:
  
             return the accpars potential parameters for use of this potential with NEMO
  
          INPUT:
  
             vo - velocity unit in km/s
  
             ro - length unit in kpc
  
          OUTPUT:
  
             accpars string
