Mid-infrared lines near Sgr A* exhibit no detectable variability during flares, because light-crossing and recombination timescales in the extended gas suppress responses, so the lines cannot constrain instantaneous UV flux.

Infrared Line Diagnostics Fail to Constrain Sgr A*'s UV Output
Mid-infrared lines near Sgr A* exhibit no detectable variability during flares, because light-crossing and recombination timescales in the extended gas suppress responses, so the lines cannot constrain instantaneous UV flux.
