Notes:

1 The observed pulsational period is listed, with the periods for both modes listed for recognized overtone pulsators and the expected period for fundamental mode pulsation being indicated for suspected overtone pulsators.

2 The list includes only clusters or groups for which there are reasonably strong reasons to believe that the identified Cepheids are potential members, despite some controversy over individual objects. There is an equally long list of clusters that share the fields of Cepheids and that are less strongly indicated to share a physical association. Contact the author of this Web site for details.

3 Generally the most recent study of the associated cluster or group is listed.
