In the original figure the left hand panel was printed twice. The correct figure is given below.


[FIGURE] Fig. 2. An absorption feature and a soft excess are clearly evident in the LECS residuals when a power law ([FORMULA], NH =N [FORMULA]) is fitted the the data (left panel). Data are well parameterized by a broken power-law plus a notch (right panel)
