- Naomi summarized the work on dE/dx comparisons between measured and sim data using the CDC space-charge correction with data from phi, rho and K+Sigma0. The ratio between corrected measured and sim has little dependence on momentum, and dE/dx from amplitude is similar for p, K and pi in all channels studied (integral is more variable). The scaling factors necessary to match the measured corrected data to the sim are now in CCDB (/CDC/dedx_theta/dedx_amp_scale). They are different for 2017 because the gains were calibrated to match an older simulation. The scaled corrected dE/dx is consistent between run periods and shows good agreement between measured and sim, except that the simulated resolution is better.
