... profile¹

A King profile has the form $A(1/([1+(r/r_c)^2]^{\alpha}))$, where $r$ is the radial distance from the centre of the PSF, $r_c$ is the core radius and $\alpha$ is the slope of the King model.

... lists.²

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.

... passage)³

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.

...uhb:fig:epic_sens⁴

The 5$\sigma$ value represents a relatively conservative limit which crudely takes into account the fact that there are additional systematic background effects which have yet to be characterised in detail. For the effective beam area of XMM-Newton, the appropriate limit for purely Poissonian background fluctuations to yield $\le 1$ spurious source per field is about 3.5 - 4$\sigma$.

... time⁸

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 $\simeq$0.1740 ms. The sum of the frametransfer time and of the time needed to read out all the pixels in the storage area 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.

... tables⁹

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.
