Photoelectric search for CP2-stars in open clusters. XIII - NGC 3114 and IC 2602 Delta-a photometric observations of two open clusters, obtained usingthe 50-cm and 1-m telescopes at ESO during 1981-1984, are reported. Thedata are presented in extensive tables and graphs and brieflycharacterized. Of the 168 stars measured, eight (six in NGC 3114 and twoin IC 2602) are identified as chemically peculiar upper-main-sequenceobjects with magnetic fields. These hot CP2 stars are found to beblueshifted relative to the cluster main sequences on the V/(b-y)diagrams.
Stromgren photometry of open clusters. IV - NGC3114 and additional measurements for IC2602 Stromgren photometry of 122 B- and A-type stars in the southern opencluster NGC3114 up to V = 12.mag is presented. The membership of theobserved stars is discussed; a mean reddening of E(b-y) = 0.043 for thecluster is estimated; and the behavior of CP stars in the color diagramsis investigated. Furthermore, additional measurements for 16 stars inthe cluster IC2602 are given, and the membership of these stars isexamined.
