Hardness ratios {#hardness}

![The hardness ratio from the pn detector (see section \[hardness\]) for NGC 2547 members versus overall count rate in the pn detector, versus $B-V$ and versus $V-I$. Indicated against the y-axis of each plot are the emission measure ratios of the hot to cold components that would provide that observed hardness ratio in a simple 2-T coronal model with $T_{1}=0.6$keV and $T_{2}=1.5$keV. The dashed line in the upper plot is a simple straight line fit to the data.
