Hi Alex,

The lead author gives their e-mail address, so you could contact them for clarification.

Yes I have done. We’ll see what comes back. Fig 4 has error bars which are clearly nowhere near 50x wider for the SPAD data which if the 50 fold figure is correct, implies the uncertainty is determined by factors other than the SNR. At 50ms sample rate I would expect scintillation to be a significant factor in the uncertainty, though there seems to be perhaps some interesting correlation in the fine detail between the two measurements during egress which cannot be due to scintillation.
