J/ApJ/612/848          Chandra LMXB in NGC 1332                (Humphrey+, 2004)

A Chandra view of the normal S0 galaxy NGC 1332. I. An unbroken, steep power-law luminosity function for the low-mass X-ray binary population. Humphrey P.J., Buote D.A. <Astrophys. J., 612, 848-859 (2004)> =2004ApJ...612..848H
ADC_Keywords: X-ray sources ; Binaries, X-ray Keywords: galaxies: elliptical and lenticular, cD - galaxies: individual (NGC 1332) - X-rays: binaries - X-rays: galaxies Abstract: Chandra ACIS-S3 (Advanced CCD Imaging Spectrometer) observations of the nearby S0 galaxy NGC 1332 resolve much of the X-ray emission into 73 point sources, of which 37 lie within the D25 isophote. Description: The region of sky containing NGC 1332 was observed with the ACIS (Advanced CCD Imaging Spectrometer) instrument aboard Chandra between 2002 September 19 10:39 and September 20 02:59 UTC.

Note (1): The count rate column quotes count rates not corrected for exposure map variations. Note (2): The comment abbreviations are as follows: A = absorbed spectrum; B = soft spectrum; C = close to chip edge (flux may be unreliable); E = extended; G = coincident with a globular cluster (GC); NG = in the WFPC2 FOV but not coincident with a GC; R = also seen with ROSAT; V = variable.
