This paper discusses some aspects of the estimates of Higgs boson coupling
sensitivities for LHC and ILC presented at the Snowmass 2013 meeting. I
estimate the measurement accuracies underlying the CMS presentation to
Snowmass. I present new fits for the ILC capabilities. I present some joints
fits to prospective LHC and ILC data that demonstrates the synergy of the
High-Luminosity LHC and ILC programs. Contributed to the proceedings of the
Snowmass 2013 Community Summer Study.Comment: 23 pages, 4 figures; v3 - minor clarifications adde
