type A ====== L94: "both ... and" instead of "either .. or"? L98: "uncertainty on" instead of "in"? L136: Does a comma before any verb in the sentence make sense? L141: "Therefore" sounds as if "assigning one b-jet to the top decay" is a direct consequence of "there is a high-eta jet". A combining instead of causal connector is better. Fig. 1: in the labels, gamma and mu should be bold as is the rest of the text type B ====== L21-23: Since this is still the introduction, describe the expectations rather than the result. L123: "Events must contain exactly three loose leptons". But then, only events with at least two tight leptons are used, even for the sidebands. To highlight that a fourth loose lepton is vetoed, write that explicitly. L125: "world-average Z boson mass" - is really 91.1876 GeV used, or rather just 91 GeV? In the latter case, I would drop rather drop the "world-average". L149: How is this sensitive to whether there was a top or an anti-top in the event? Or is there any other charge used as well? L233-235: Why can you do that? Wouldn't theoretical uncertainties give additional shape uncertainties that you cannot cover by just using control regions? L263-265: What's the benefit of publishing per-year results? I would drop this sentence.
