Abstract:
We carried out near- to mid-infrared imaging and spectroscopic
observations of patchy areas in the Small Magellanic Cloud using the
Infrared Camera aboard AKARI. Two 100arcmin2 areas were imaged in
3.2, 4.1, 7, 11, 15, and 24um, and also spectroscopically observed
in the wavelength range continuously from 2.5 to 13.4um. The spectral
resolving power, λΔλ, values were about 20, 50,
and 50 at 3.5, 6.6, and 10.6um, respectively. Other than the two
100arcmin2 areas, some patchy areas were imaged and/or
spectroscopically observed as well. In this paper, we overview the
observations and present a list of near- to mid-infrared photometric
results, which lists ∼12000 near-infrared and ∼1800 mid-infrared
bright point sources detected in the observed areas. The 10σ
limits are 16.50, 16.12, 13.28, 11.26, 9.62, and 8.76 in Vega
magnitudes at 3.2, 4.1, 7, 11, 15, and 24um bands, respectively.
