I am a confused how the photosynQ documentation and other publications that define the gH+ and vH+ measurements.

What does the MultispeQ Measure and how to cite sections of the photosynQ documentation define vH+ and gH+ as proton conductivity and steady state proton flux, respectively.

However, Avenson et al. (2005) defines vH+ as the steady-state rate of photon flux, and Kanazawa and Kramer (2002) defines gH+ as proton conductivity. Does the photosynQ documentation have the definitions of vH+ and gH+ transposed?

AVENSON, T.J. et al., 2005. Integrating the proton circuit into photosynthesis: progress and challenges. Plant, Cell and Environment, 28(1), pp.97–109. Available at: http://dx.doi.org/10.1111/j.1365-3040.2005.01294.x.

Kanazawa, A. & Kramer, D.M., 2002. In vivo modulation of nonphotochemical exciton quenching (NPQ) by regulation of the chloroplast ATP synthase. Proceedings of the National Academy of Sciences, 99(20), pp.12789–12794. Available at: http://dx.doi.org/10.1073/pnas.182427499.

Hi Craig, You found a typo in the Parameter section. Yes, gH+ is the proton conductivity, and vH+ is the flux. We will fix it. Thank you for pointing out. Atsuko

It looks like they already made the correction.
