is described in $HEADAS/bin/xselect.mdb, where $HEADAS is the UNIX shell environment variable set by
running heainit, or an equivalent HEASoft initialization.

The Poisson probability that an X-ray event has another X-ray event
within the STATUS[4] window,
=2
0.72 msec, is
where
is the source X-ray count rate.
The false coincidence rate is given by multiplying this probability by the source count rate,
.
This rate exceeds the frame rate 0.02 cts/s when
3.7 cts/s.

- The Ls grade has been considered as an X-ray event grade, but the onboard calibration found that most Ls events originate from background particles or secondary X-ray events, so we do not include Ls in this list. This does not apply for Bright sources. See Section 6.4 for details.

- The Resolve response generator can produce an RMF file
for a mixed event grade (e.g., Hp+Mp) spectrum, but we do not recommend an analysis with such
a spectrum at this moment as a quality difference of the spectral resolution and/or gain
between grades is significant.

The ALLPIX option includes pixel 12, but since the science event file does not include
pixel 12 events, it is equivalent to pixlist=0-11,13-35.
