Abstract:
Using the XMM-Newton observatory, we have observed the peculiar Of?p
star HD 191612. The field contains a hundred individual X-ray sources.
In this table we present the average X-ray count rates of these
sources and their cross-identifications with several catalogues.
Description:
A detection algorithm (SAS task edetect_chain) was applied to all EPIC
data, except to those of 2005 Apr. 17 (Rev. 981) which are too noisy
to reveal the presence of faint sources. As a source can appear in a
CCD gap or outside the field of view for one particular instrument at
a given revolution but not at another one, we have determined the best
combination of revolutions and instruments to be used for each source.

Note (1): Average count rate measured on the best combination of observations.
If not listed, it means that the source was not observed by this
instrument (source in a gap or out of FOV).
Note (2): HR1 is defined as (M-S)/(M+S) with S and M the count rates
in the 0.4-1keV and 1-2keV energy bands, respectively
Note (3): HR2 is defined as (H-M)/(H+M) with M and H the count rates
in the 1-2keV and 2-10keV energy bands, respectively
Note (4): Number of counterparts within 3 arcsec of the X-ray source.
If more than one, the counterparts' properties are not listed.
