Increased diagnostic capability of the EUV Imaging Spectrometer (EIS) aboard Hinode (former Solar-B) has been demonstrated with a set of iron emission lines emerging in the two EIS observing wavelength bands (170–210 Å and 250–290 Å) and their line-intensity ratios. “Abundance-uncertainty” free relative emission measure distributions as a function of temperature were deduced using only iron emissi...
