CO₂ monitoring, useful explainer
Here's my own explainer about CO₂ monitoring.
It covers some of the same topics as the one above, but filling in more background knowledge. When I wrote it, I was thinking of e.g. a teacher with lots of knowledge about children and not much knowledge about science, who just wanted to make their classroom safer from covid.

The bright black hole X-ray binary 4U 1543-47 during 2021 outburst. A clear state transition from super-Eddington to sub-Eddington accretion revealed by Insight-HXMT
We present a detailed analysis of the observations with the Hard X-ray Modulation Telescope of the black hole X-ray transient 4U~1543-47 during its outburst in 2021. We find a clear state transition during the outburst decay of the source. Using previous measurements of the black-hole mass and distance to the source, the source luminosity during this transition is close to the Eddington limit.
