We use the relativistic distorted wave impulse approximation to analyze data on 16O(e,ep)15N at |Q2|<~0.4(GeV/c)2 that were obtained by different groups and seemed controversial. Results for differential cross sections, response functions, and ATL asymmetry are discussed and compared to different sets of experimental data for proton knockout from p1/2 and p3/2 shells in 16O. We compare with a nonrelativistic approach to better identify relativistic effects. The present relativistic approach is found to accommodate most of the discrepancy between data from different groups, smoothing a long standing controversy.
