3.7.1 A comparison of XMM-Newton vs. Chandra

The main difference in instrument operation between XMM-Newton and Chandra is that on XMM-Newton all instruments operate simultaneously, unless prohibited by constraints (§ 4.2), while on Chandra they are alternated.

Further differences between Chandra and XMM-Newton, in addition to the ones summarised in Table 28, are shown below.
