Corrigendum to“Modeling the gain of inner-shell X-ray laser transitions in neon,argon,and copper driven by X-ray free electron laser radiation using photo-ionization and photo-excitation processes”[Matter Radiation Extremes 1(1)(2016)76-81]

Corrigendum text:There is a misprint in the text of Figs.3 and 4.The text on the bottom part of Figs.3 and 4 should be“100 fs pulse Photoexcitation”and“1 fs pulse Photoexcitation”respectively.This error does not affect any conclusions in this work,and it has been corrected in the printed version of the journal.
