Abstract:
Using the data from the NOAO Local Group Survey, we have measured the
Hα fluxes of 291 nebulae associated with 21 of the van den Bergh
OB associations. We have combined these data together with six-color
HST WFPC2 photometry, in order to identify the most UV-bright stars in
the region. The simple purpose of this article is to explore the
spatial relationships between these components.
Description:
The HST stellar data are from The Bianchi et al. (2011,
(http://dolomiti.pha.jhu.edu/LocalGroup/) HST program (GO-11079).
The images from the NOAO Local Group Survey (Massey et al., 2007, Cat.
J/AJ/134/2474) provided images at Hα for all of the selected
regions. We combined the images as necessary to provide a complete
coverage of each HST field.
