H II regions and the extinction of Cepheids in NGC 2403

Journal Article:

Abstract

Spectrophotometric observations of H II regions can be used to constrain the extinction of Population I objects in external galaxies. An analysis of NGC 2403 reveals that the Cepheids used to determine the distance are reddened on average by less than 0.2 mag. Either they are redder intrinsically than the Cepheids used to calibrate the PLC relation, or their photometry suffers from systematic errors.
