Hi Céline,
I think the answer may be in your question, actually.
The Doschek ''et al.'' article states a single number, but that is based on comparisons with older data. However, it is still consistent with the numbers derived from comparing the pre-launch laboratory EIS calibration data with the on-orbit EIS data by Brown ''et al.'' (2008). The Brown ''et al.'' numbers are inferred widths, but the reasoning is pretty logical; the fact that the Doschek ''et al.'' (2007) number falls within that range of 0.054nbsp;— 0.057nbsp;Å is comforting.
In summary, Brown ''et al.'' (2008) infer an instrumental width of 0.054 Å in the short-wavelength channel (170 —
210 Å) and 0.057 Å for the long-wavelength channel (250 — 290 Å)
