Table 2:

Relative differences between metal measurements made with the three EPIC instruments MOS1, MOS2 and pn computed over the whole sample.

For each element in the first line only statistical errors are accounted for, in the second line a $3\%$ systematic error is added in quadrature to each abundance measurement (see discussion in Sect. 4.3).
