Description Usage Arguments Value
. This function calculates three key parameters and addes, or mutates, them to the input tibble.

.tbl |
tibble. |
calb |
signal amplitude corresponding to 1 mL O2 which was injected for the calibration, unit: grid. |
positive_pmax |
a slope corresponding to net O2 evolution rate under repeatitive single-turnover flashes and weak far-red light, unit: grid min^-1. |
negative_pmax |
a slope corresponding to O2 uptake rate under weak far-red light, unit: grid min^-1. |
positive_psii |
a slope corresponding to net O2 evolution rate under repeatitive single-turnover flashes and weak far-red light, unit: grid min^-1. |
negative_psii |
a slope corresponding to O2 uptake rate under weak far-red light, unit: grid min^-1. |
amp_pmax |
an expansion coefficient, no-unit. |
amp_psii |
an expansion coefficient, no-unit. |
leaf_area |
an area of the enclosed leaf in the chamber, unit: m^2. |
hz |
a frequency of single-turnover flash, unit: s-1, default: 10. |
e_per_o2 |
a number of electron consumed in PSII to evolve one O2, unit: mol mol^-1, default: 4. |
artefact |
a factor to correct non-photosynthetic signal, i.e. heating by irradiance, unit: grid min^-1. |
