Abstract:
A variety of interesting objects such as Wolf-Rayet stars, tight OB
associations, planetary nebulae, X-ray binaries, etc., can be discovered
as point or compact sources in Hα surveys. How these objects
distribute through a galaxy sheds light on the galaxy star formation
rate and history, mass distribution, and dynamics. The nearby galaxy
M33 is an excellent place to study the distribution of Hα-bright
point sources in a flocculant spiral galaxy. We have reprocessed an
archived WIYN continuum-subtracted Hα image of the inner 6.5'x6.5'
of M33 and, employing both eye and machine searches, have tabulated
sources with a flux greater than approximately 10-15 erg/cm2/s. We
have effectively recovered previously mapped H II regions and have
identified 152 unresolved point sources and 122 marginally resolved
compact sources, of which 39 have not been previously identified in
any archive. An additional 99 Hα sources were found to have
sufficient archival flux values to generate a Spectral Energy
Distribution. Using the SED, flux values, Hα flux value, and
compactness, we classified 67 of these sources.
Description:
Images centered on the nucleus of M33 were made through two separate
filters by Roming (1998PhDT.........7R 1998PhDT.........7R) with the WIYN telescope on
October 17 and 18, 1995. The field of view (FOV) of each image is
6.5'x6.5' square with a sampling of 0.197"/pixel on a 2kx2k CCD
detector. The filters used were Hα centered at 6565.0 Å, with
a full width at half maximum (FWHM) of 47 Å, and a continuum filter
centered at 6409.0 Å, with an FWHM of 28 Å. Seven individual
exposures of 400-600 s duration were obtained in each filter for a
total exposure time of 3100 s in each.

for a planetary nebula, while smaller values indicate a stronger continuum
such as for stars embedded in gas.
Note (2): Following the convention in Hodge et al. (2002ASSL..221.....H 2002ASSL..221.....H),
nebulae catalogued by Boulesteix et al. (1974A&A....37...33B 1974A&A....37...33B) are enumerated
with no prefix letter, those catalogued by Courtes et al.
(1987A&A...174...28C 1987A&A...174...28C) have the prefix "Z", and those catalogued by
