Model M1
Optical model
Mirrors are not a number. They are a stripe of heat on a pipe. Move the tracker and watch the hot stripe walk off the tube. Geometric concentration only sizes the hole. The coating sees the map.

Receiver-plane flux
Rows are transverse across the aperture. Columns run along the rail. A 50× pod is not 50 suns. Mean concentration here is η_opt × Cg.

What the coating sees
Intercept vs tracking error
Other inputs held at the current settings. Past ~6–8 mrad the CPC starts to miss and peak-to-average climbs. That is G3, not a bigger mirror.
