- An event list is a table with one line per received
event, listing (among others) attributes of the events such as the
x and y position at which they were registered, their arrival time
and their energy.

- The Target Visibility Checker, a tool to check the visibility of any target in the
sky for XMM-Newton, provides also information on the orbital phase when the target
visibility starts and ends.

- The 5 value represents a
relatively conservative limit.
For the effective beam area of XMM-Newton, the appropriate
limit for purely Poissonian background fluctuations to yield spurious
source per field is about 3.5 - 4.

- ... time6
-
Frametransfer time is the time needed to
transfer the charge accumulated on the continuously exposed
CCD during an integration time into the storage area.
It amounts to 0.1740 ms. The sum of the integration time
and the frame transfer time is the frametime. The frametime depends on the sizes,
shapes and positions of the windows. For a full frame it amounts
to about 11 ms. The only time when source photons are not
properly recorded by the detector is during charge transfer.
Therefore, the deadtime is equal to the frametransfer time.

- In this
section the reader will find two types of “offsets”: “offset
tables” for the zero level of charge measurements in EPIC cameras (see
§ 3.3.6) and “pointing offsets” for the
distance between adjacent telescope pointings.
