AKARI Near-infrared Spectral Atlas of Galactic HII regions (Mori+ 2014) ================================================================================ Observational Studies on the Near-Infrared Unidentified Emission Bands in Galactic HII Regions Mori, T.-I., Onaka, T., Sakon, I., et al. =2014ApJ...784...53M ================================================================================ ADC_Keywords: H II regions ; Spectra, infrared Mission_Name: AKARI Keywords: dust, extinction-infrared: ISM Description: This catalog contains 464 near-infrared spectra of Galactic HII regions. The observations were performed for 36 different sources by the use of "Ns" or "Nh" slit (0.8 arcmin length 5 arcsec width for Ns or 1 arcmin length 3 arcsec width for Nh, see Onaka et al. (2007) for more detailed information on the instrument). The target sources were basically selected from Galactic ultra-compact and giant HII regions catalogued by Crowther & Conti (2003) and Conti & Crowther (2004) according to the visibility of the satellite. Generally, two pointing observations were performed for each target, whereas some targets were observed only once. Each pointing observation is identified by an observation ID (Obs-ID). In the observations, grism and prism spectroscopy were done separately for the same slit area in the fist and the latter half of a single pointing observation. We extract spectra taken with the grism and the prism mode respectively from the same area with the length of 6 pixels (8.76 arcsec) and the width of 5 arcsec for the Ns slit or 3 arcsec for the Nh slit one by one along the slit direction. As a result, we obtain several sets of grism and prism spectra (2.5-5.0 micron, R~100 for the grism and 1.7-5.4 micron, R~20-40 for the prism) from each pointing observation. Each spectra-extracted region is identified by a position number inside a slit (poN). See Mori et al. (2014), for details.
