Example of data analysis in an observed region (ObsID = 1100298_001). (a), (b) Point-source extraction from short- and long-exposure reference images. Red circles enclose positions of the extracted point sources. The green box corresponds to Area 1 in figure 3. (c), (d) Spectral images with two dispersers, SG1 and SG2. The spectra were extracted from the regions enclosed in the boxes. The circles enclose the zero-th order light of sources A and B. (e), (f) Spectra extracted from sources A and B. The blue and green curves plot the SG1 and SG2 spectra, respectively, output from the spectroscopic toolkit, while the orange curve indicates the final spectrum after the absolute flux calibration using the AKARI 9 μm flux (red data point).
