about the independence of the test, you are wrong it was independent, since rossi did not build the installation to test, and testers were free to do what they wanted out of the reactor. You show you bias by refusing that fact.
the emissivity is a key factor, and the physicist screwed up, in that context, not to check the tables with a good calibrations.
about the temperature assuming emissivity is 0.9, we all mostly agree, that it is around 750C.
You story about T^2.1 seems very strange for me... you seems to say that the bolometer sensitivity is strongly wavelength dependence... I imagine the documentation is referenced in your report...
My computation is based on a flat wavelength response, and is quite robust under that assumption.
Note that some state that you use the low temperature version of the Optris documentation, and I never considered that argument under my model of flat response. if response heavily depend on the bolometer array characteristics, it is a point to restudy.
About calorimetry, Ferrara test is perfectly calibrated, and fairly independent (reactor could be inspected and was inspected without opposition), so it worked.
Lugano was fully independent, abandoned alone to the testers, and unfilled by the testers (despite the misunderstanding).
I don't exclude the test was badly done, but it is very strange that Rossi did not notice his reactor was so cold. and if he was fooling the testers, this protocol was suicidal.
If a scientist used a good multiband bolometer, a thermocouple, or known emissivity dots he would have seen the problem - they even tested known emissivity dot but they fall of it seems - so Rossi did not oppose that.
Theory of fraud is impossible to support honestly.
Even the hypothesis of emissivity at 0.9 or 0.4 seems to neglect the effect of short wavelength transparency on radiation, and internal metallic reflectivity. The Dogbone are really complex for optical calorimetry, and calibration was required. I would propose that since the dogbone is fat and opaque inside, then the emissivity should not assume any effect of transparency... Fins and surface state may also change emissivity (some say it reduce reflectivity, thus increase emissivity).
It does not impact normally the temperature since alumina is opaque in Optris range.
It looks like a screw-up caused by abuse of theory, but it is not even sure.
About Isotopic measurement, Bo Hoistad say clearly that Rossi was present but did not extract the samples himself. He just controlled the quantity was minor. You show your bias by refusing that fact again.
