data frame of dimensions 16 by 4.
assimilation as measured in Naidu et al. (2003) in
Miscanthus. The first column is the observed net
assimilation rate (\mu
mol m^{-2}
s^{-1}
)
The second column is the observed quantum flux (\mu
mol m^{-2}
s^{-1}
) The third column is the
temperature (Celsius). The fourth column is the observed
relative humidity in proportion (e.g. 0.7).
