Abstract:
We present an X-ray study of our nearest starburst galaxy IC 10, based
on XMM-Newton and Chandra observations. A list of 73 XMM-Newton and 28
Chandra detections of point-like X-ray sources in the field is
provided; a substantial fraction of them are likely stellar objects in
the Milky Way due to the low Galactic latitude location of IC 10.
Description:
The XMM-Newton observations were taken on 2003 July 3 with a total
exposure time of ∼45ks for the EPIC-MOS cameras and ∼42ks for the
European Photon Imaging Camera (EPIC) PN camera. We use only the data
from the PN camera (with a thin optical blocking filter) because of
its high sensitivity to soft X-rays in the study of diffuse emission
and include the data from the MOS cameras in the analysis of X-1.

Global notes:
Note (G1): Position uncertainty (1sigma) calculated from the maximum
likelihood centroiding
Note (G2): Sum of the exposure-corrected count rates in the four bands
Note (G3): S=S1+S2, H=H1+H2 and B=S+H.
Hardness ratios are listed only for values with
uncertainties less than 0.2
Note (G4): Tabel 'B', 'S', or 'H' mark the band in which a source is detected
with the most accurate position that is adopted in column DX.
