jmax_temperature_param_flat

Parameters that describe a flat temperature response (in other words,
 no dependence on temperature) for Jmax-related photosynthetic
 parameters, intended to be passed to the
 <code>calculate_temperature_response</code> function.

jmax_temperature_param_flat function

List with 2 named elements that each represent a variable whose
 temperature-dependent value can be calculated using a polynomial equation:<ul>
<li><code>alpha_j_norm</code>: The apparent quantum efficiency of electron
 transport (<code>alpha_j</code>) normalized to its value at 25 degrees C.</li>
<li><code>theta_j_norm</code>: The empirical curvature parameter normalized to
 its value at 25 degrees C.</li>
</ul>In turn, each of these elements is a list with 3 named elements:<ul>
<li><code>type</code>: the type of temperature response.</li>
<li><code>coef</code>: the polynomial coefficients.</li>
<li><code>units</code>: the units of the corresponding variable.</li>
