Previously Claimed(/Unclaimed) X-ray Emission Lines in High Resolution Afterglow Spectra

Astrophysics 2009-11-10 v1

Abstract

We review the significance determination for emission lines in the Chandra HETGS spectrum for GRB020813, and we report on a search for additional lines in high resolution Chandra spectra. No previously unclaimed features are found. We also discuss the significance of lines sets reportedly discovered using XMM data for GRB011211 and GRB030227. We find that these features are likely of modest, though not negligible, significance.
