Abstract:
    This work presents UBV photometry of the stellar populations
    associated with seven superbubble nebulae and five classical H II
    regions in the Large Magellanic Cloud. Although the nebular morphology
    of the superbubbles appears to be substantially evolved compared to
    the classical nebulae, the color-magnitude diagrams do not reveal any
    noticeable correlation between the resident stellar population and
    nebular morphology. The photometry presented here will be used in a
    forthcoming paper to examine further the stellar content and dynamics
    of these superbubbles.

Description:
  Tables 4a-m provide the photometry for the OB associations of the
  sample, including both superbubbles and diffuse H II regions.  Notes
  for individual objects are:
  DEM 31:  Photometry for D31-2001 (Sk -67 17) listed from
           Ardeberg et al. (1972A&AS....6..249A)
  DEM 106: Stars with prefix D106A- have V photometry from a separate,
           short exposure.
  DEM 192: Stars with prefix D192A- have V photometry from a separate,
           short exposure.
  DEM 301: Photometry for D301-1005 listed from Massey et al.
            (1995ApJ...438..188M)

  Postscript versions of the plates in Figure 1 of the printed paper
  are included.  Each is a V image of the OB association field,
  with bright stars identified.  The remaining stars can be identified
  with the aid of coordinates given in Table 4a-m.  Each individual
  frame is 3.8' x 3.8' square, with north up and east to the left.

Note on ID:
  Star identification.  Stars with a and b components are
  spectroscopic binaries, whose V magnitude has been estimated as
  described in the printed paper.  However, the colors listed for both
  components are the original, combined colors determined for the
  composite object.  The DAOPHOT errors for these objects are
  misleading, and have been deleted.
Note on e_Vmag, e_B-V, e_U-B:
  These are the photometric errors computed by DAOPHOT and do not
  include systematic effects such as those introduced by aperture
  corrections and transformation errors.
