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.
