H1和ZEUS公布的PDF分析进行了比较，包括相关的系统不确定性的不同处理的讨论。通过对H1数据集进行PDF分析以及分别对ZEUS和H1数据集进行相同（ZEUS）分析，研究了数据集和分析的差异。最后，将HERA平均数据集进行ZEUS PDF分析，并将结果与将ZEUS和H1数据集一起进行该分析时获得的结果进行比较，同时使用 处理相关系统不确定性的偏移量和海森方法。
The H1 and ZEUS published PDF analyses are compared, including a discussion of the different treatments of correlated systematic uncertainties. Differences in the data sets and the analyses are investigated by putting the H1 data set through both PDF analyses and by putting the ZEUS and H1 data sets through the same (ZEUS) analysis, separately. Finally the HERA averaged data set is put through the ZEUS PDF analysis and the result is compared to that obtained when putting the ZEUS and H1 data sets through this analysis together, using both the Offset and the Hessian methods of treating correlated systematic uncertainties.
