Exposure to our blackbody at various Z+Z₀ distances: theoretical E_th and measured E_m irradiance on [1,000; 2,500nm], and estimated by theory E_IR,th and CatRayon E_IR,CR⁵ and camera picture analysis E_IR,pc on [780; 3,000nm]. At 800 celsius and 97 and 492 mm measurements failed. At 1,100 celsius and 97 mm the camera and the blackbody were a little misaligned. They were too misaligned at 1,200 celsius and 172 mm.
