Abstract:
An extensive photometric dataset has been compiled for six Luminous
Blue Variables (LBVs). The dataset comprises published and unpublished
measurements in the Stroemgren, Geneva and Walraven photometric
systems. The measurements within each individual system are presented
in a uniform manner. Combining observations from these three
photometric systems, a VJ light curve has been constructed for each
LBV. Examination of the light curves reveals variations on widely
different magnitude and time scales.
For explanation about the photometric sytems, see the definitions
in the General Catalogue of Photometric Data:
