Notes. Intensities are in erg s-1 cm-2 sr-1 for EIS, and in arbitrary units for XRT. C- and P- correspond respectively to boxes in the corona and in the prominence. P-3 corresponds to the hole seen in Hα. For each EIS line, the first row corresponds to intensity values with a constant background removed from the spectrum. The second row (values between brackets) has no background subtraction. The uncertainty in radiometric calibration of EIS data is of the order of 22% (Lang et al. 2006).
