This dataset contains the raw data underlying the results presented in “Impact of a photoemission resonance on the measured transition time scale in solid state photoemission”. The data were obtained using spin-resolved angle-resolved photoemission spectroscopy (spin-resolved ARPES) at the COPHEE endstation of the Swiss Light Source (Paul Scherrer Institut), on TiTe2 and TiSe2 samples. Sample names are in the file names. The data can be processed using Igor Pro. The files correspond to the measurements shown in Figs. 1(a)–(d), 2, and 3 of the associated manuscript.
