\hline \hline
Flag & Description & Definition for flag to be set True (cf.\ Notes) \\
\hline
1 & Low detector coverage & $m_{\rm camera} <  0.5$ \\
2 & Near other source & $r \le 65 \cdot \sqrt{R_{\rm epic}}$~ AND  $r_{\rm min} =
10\arcsec$ AND  $r_{\rm max} = 400\arcsec$ \\
3 & Within extended emission & $r \le 3 \cdot E$~ AND $r_{\rm max} = 200\arcsec$ \\
4 & Possible spurious extended detection near bright source & Detection is
extended AND Flag~2 is set
    AND $c_{\rm epic} \ge 1000$ \\
5 & Possible spurious extended detection within extended emission & Detection is
extended AND $r \le
    160\arcsec$ AND fraction of rate compared with originating source is $\le$$0.4$ \\
6 & Possible spurious extended detection due to unusual large single-band
    detection likelihood & Detection is
extended AND fraction of detection likelihood per camera and
    band compared with the sum of all is $ \ge$$0.9$ \\
7 & Possible spurious extended detection & At least one of the flags~4, 5, 6 is set \\
8 & On bright MOS1 corner or bright low-gain pn column  & Source position
    is located on one of the affected pixels \\
9 & Near bright MOS1 corner & Source position within $ r_f = 60\arcsec $ of a bright corner pixel \\
10 &  Not used &  \\
11 &  Within region where spurious detections occur  &  Set manually \\
12 &  Bright (``originating'') point source in region where spurious detections
      occur & Set manually \\

  Notes:  $m$ is the detector coverage of the detection weighted by the
PSF; $r$ is a radial distance in arcseconds from the ``originating'' source
within which all detections receive this flag; $R_{\rm epic}$ is the EPIC
source count rate in ct/s of the ``originating'' source; $E$ is the extent
parameter (core radius) of the ``originating source'' in arcseconds (cf.\
Sect.~\ref{extdsrc}); $c_{\rm epic}$ is the EPIC source counts of the ``originating''
source; $r_f$ is the radius used for source PSF fitting in arcseconds.
