Table 1
Typical background values for the pointing simulations.
| Photon background | Particle background | |||
| soft band | hard band | soft band | hard band | |

||||
| MOS1 | 1.21 | 1.77 | 0.764 | 1.16 |
| MOS2 | 1.32 | 1.88 | 0.730 | 1.09 |
| PN | 2.49 | 3.55 | 2.80 | 6.03 |
Notes. We allowed the particle background to vary from one pointing to the other through a multiplicative factor chosen among 0.1, 0.25, 0.5, 1, 2, 4 and 8. Units for each XMM-Newton detector are 10-6 cts s-1 pixel-1.
