a) Images of our targets taken by AKARI with the N3 filter (2.7−3.8   μm). The stellar light is dispersed from right (short wavelength) to left (long wavelength). The FOV is 1′ × 1′. The coordinate at the center of the FOV is listed in Table 1. Images of IRC-L1041-2 and 2MASS  J1628137-243139 are damaged by cosmic rays, while images of HV Tau, HK Tau, ASR41, and UY Aur are affected by saturation and column pull down. b) Spectral images of 1527 and IRAS  04302.
