Abstract:
Optically bright Galactic stars (V≲13mag) having fnu(24um)>1mJy are
identified in Spitzer mid-infrared surveys within 8.2deg2 for the
Bootes field of the NOAO Deep Wide-Field Survey and within 5.5deg2
for the First Look Survey (FLS). One hundred and twenty-eight stars
are identified in Bootes and 140 in the FLS, and their photometry is
given. (K-[24]) colors are determined using K magnitudes from the
Two Micron All Sky Survey for all stars in order to search for excess
24um luminosity compared to that arising from the stellar photosphere.
Description:
The Bootes MIPS survey was obtained for the 8.2deg2 within the
Bootes field of the NDWFS. This survey was done as part of Spitzer
Guaranteed Time Observations by J. Houck and M. Rieke, and a catalog
of 24um sources (not yet published) was produced by E. Le Floc'h.

Note (1): Flags as follows:
c = Star identified in Fig. 1 as having 24um excess, with (K-[24])>0.2mag
d = Variable star from Akerloff et al. (2000, Cat. J/AJ/119/1901)
e = Sources 87 and 88 are a close double star without individual
J,H,K magnitudes, spectral types, and proper motions
Note (2): Color uses magnitude at 24um determined from S24um with zero
magnitude corresponding to S24um=7300mJy.
Note (3): Estimated from (V-K) color; luminosity class V (main sequence) is
assigned for stars whose upper luminosity limit is MV>4, based on
proper motions as discussed in text.
