VizieR Online Data Catalog: New X-ray-selected SNRs detection with Chandra (Leonidaki+, 2010)

The sample used for this study consists of six nearby galaxies: NGC 2403, NGC 5204, NGC 4395, NGC 4449, NGC 3077, and NGC 4214. These galaxies are selected from the Third Catalog of Bright Galaxies (RC3; de Vaucouleurs et al. 1995, Cat. VII/155) to be (1) late type (T>4; Hubble type), (2) close (=<5 Mpc) in order to minimize source confusion (at 5 Mpc, 1"~25 pc), (3) at low inclination (=<60°) in order to minimize internal extinction and projection effects, and (4) be above the Galactic plane (|b|>20°). All exposures were obtained with the back-illuminated Advanced CCD Imaging Spectrometer ACIS-S3 CCD chip (pixel size: 0.49"x0.49"; energy resolution ~120 eV at 1 keV; Garmire et al. 2003SPIE.4851...28G) at the focal plane of the High Resolution Mirror Assembly (van Speybroeck et al. 1997SPIE.3113...89V).
