| NH = 3.4(1022 cm-2) Assumed distance: 21kpc ( Becker & Helfand, 1984 ) | - nH was derived by simultaneously fitting outer shell(two thermal plasma model) and central region(power-law)
- see fit detail page for more about the fit.
- see chandra spectrum page for region used.

This nearby source list is incomplete. All the above sources are originally from the "src2.fits" file which is distributed with standard Chandra processing. Only sources with significant count rate and which are clear to visual inspection are included.The size given above is the size of the region used in detecting that source.For each source, background was subtracted from an annular region around the source.
