我们比较了观测的非耀斑太阳日冕同时与Hinode/XRT和RHESSI。2006年11月12日，分析的日冕主要由一个单一的活动区域。对排放措施进行了比较。我们推导出发射测量分布与温度的整个活动区域从多滤波器XRT数据。如果发射来自等温等离子体，我们检查与总发射测量值估计从RHESSI测量的通量的兼容性。我们发现，RHESSI和XRT数据分析一致指向存在一个次要的排放措施组件峰值在log T 6.8-6.9。XRT和RHESSI结果之间的差异在几个因素之内，表明交叉一致性的可接受水平。
We compare observations of the non-flaring solar corona made simultaneously with Hinode/XRT and RHESSI. The analyzed corona is dominated by a single active region on 2006 November 12. The comparison is made on emission measures. We derive emission measure distributions versus temperature of the entire active region from multifilter XRT data. We check the compatibility with the total emission measure values estimated from the flux measured with RHESSI if the emission comes from isothermal plasma. We find that RHESSI and XRT data analyses consistently point to the presence of a minor emission measure component peaking at log T ∼ 6.8–6.9. The discrepancy between XRT and RHESSI results is within a factor of a few and indicates an acceptable level of cross-consistency.
