The PN energy resolution is time dependent. This effect is corrected in the RMF using the EPN_REDIST CCF.The current calibration is based on Circinus Galaxy observations performed in 2001 and 2014. A new observation of this target is required to update the correction. Circinus Galaxy is a bright Seyfert 2 galaxy and is characterised by a highly absorbed hard X-ray spectrum with a bright Fe-K fluorescent line. Comparison of the measured width of this line over time can help constrain the modelling of the time-evolution of the PN resolution. [truncated! Please see actual data for full text]

PN能量分辨率（PN energy resolution）具有时间依赖性。该效应可通过EPN_REDIST交叉相关函数（CCF）在重分布矩阵函数（RMF）中进行校正。当前校准基于2001年与2014年对圆规座星系（Circinus Galaxy）的观测数据。需获取该目标的新观测数据以更新此项校正。圆规座星系是一颗明亮的赛弗特2型星系（Seyfert 2 galaxy），其特征为具有强吸收的硬X射线光谱（hard X-ray spectrum）与明亮的Fe-K荧光线（Fe-K fluorescent line）。对该谱线随时间变化的测量宽度进行比对，可帮助约束PN分辨率时间演化的建模工作。【文本已截断！完整内容请查阅原始数据集】
