Differential efficiency of massive star formation in NGC 628
The efficiency ratio of massive star formation in the arms of the spiral NGC 628 to that in the interarm region has been determined from the sizes and positions of its H II regions following the method described in Cepa and Beckman (1989). The variation of this relative star formation efficiency with radius shows a very similar behaviour for each
