SUMMARY
The discussion focuses on calculating the emissivity of an 8000 Kelvin plasma, treated as an ideal blackbody, observed at a wavelength of 325 nm with a spectral bandwidth of 0.05 nm. The actual continuum power detected under these conditions is 1 pW. Participants express confusion regarding the treatment of continuum measurements versus specific bandwidth observations, particularly in relation to Planck's curve and the definition of emissivity in this context.
