Slightly updated. I used my blackbody calculator to derive an emissivity/temperature curve similar to Lugano fig 2. I swept the temperature form 100 to 1400, with emissivity=1, and deduced the average emissivity as Planck/StefanBoltzman using Manara's fig 5 data. The result is at http://lenr.qumbu.com/web_hotcat_pics/141022_lugano_02_manara.png Basically what happens is that as the temperature changes the peak of the blackbody spectrum moves through different parts of the emissivity/wavelength curve. The overall shape of the Lugano emissivity/temperature curve, other than the peak at 300C, is very similar to the Manara curve, so it could also be the result of a wavelength dependency. (Manara also shows a temperature dependency, but I didn't attempt to model that -- I just used the 1050K/770C curve). This increases my confidence that the calibration at 400C could still be at least qualitatively valid at 1400C
