Spectral energy distribution of a) LEDA 84274. The blue line shows the AKARI NIR spectroscopy. Squares and triangles represent the AKARI All-Sky Survey and IRAS, respectively. Crosses show the 2MASS photometry. The solid line (black) is a model template of a Sc galaxy (Polletta et al. 2007). The model line normalized at the 2MASS photometry. A dashed line (red) represents the Sc galaxy template plus three blackbody components, the temperatures of which are 600 K, 300 K, and 93 K. Dotted lines represent each blackbody component. b) Close-up of the 2 − 5 μm range of LEDA 84274, to clearly show the model and the blackbody component with 600 K. See text for details.
