ENG (Note: Some time after publication of the IDS, the designation for Engelmann was
ENG changed from EN to ENG and that for Engelhardt from ENG to ENH. This has led to
ENG considerable confusion between the two. All but three of the ENG pairs in the WDS
ENG (ENG 21, 39, and 68) were actually discovered by Engelhardt. These pairs were
ENG not renamed, however, in order to avoid confusion with already published measures)
