In particular of the depth of shower maximum, called $X_{max}$. However, uncertainties of other important parameters, in particular the multiplicity and elasticity of high energy interactions, have not improved, and there is a remaining uncertainty due to the total cross section. Uncertainties due to extrapolations from accelerator data, at a maximum energy of $\\sim$ one TeV in the p-p center of mass, to 250 TeV ($3\\times10^{19}$ eV in a cosmic ray proton's lab f","authors_text":"G.B.
