, with the same changes as in Example 2 above, and additional changes of four other lines to

vsz= 0.05   ; Size (length) of reference vector
vsp= 0.02   ; Speed         of reference vector
vd = 0.04   ; Distance between vectors
curly_on= 1 ; =1: Use curly vectors, otherwise, use standard vectors

This causes fewer and shorter vectors to be displayed, when compared to Example 2:
