AbstractWe present the current status of the AKARI slitless spectroscopic catalogue, which is produced as a part of the AKARI data archive activities. AKARI has capability of slitless spectroscopy in the NIR and MIR wavelengths for a 10' × 10' area. The data reduction is, however, very difficult due to a confusion of nearby sources after dispersion. In order to solve the problem, we first make a point source list in each FOV from the reference image, and evaluate overlaps between the spectra based on their positions and fluxes. As a trial, we applied the procedure to the Phase 2 MIR-S data (5-3 micrometers). As a result of processing all reference images of 884 spectroscopic observations, 42,000 point sources (at lambda = 9 micrometers) are extracted with a detection limit of 0.3 mJy. Based on the source list, we identified the non-overlapped sources and extracted their spectra. We obtained MIR spectra of 880 objects including main sequence stars, AGB stars, galaxies, and AGNs. The dataset is valuable as an unbiased spectral sample in the MIR. The point source and spectroscopic catalogues will be publicly released in the near future.
