Figure 2 . Example of cooling curves for bald (red; hairs
removed) and hairy (blue; hairs intact) patches adjacent to one another
on the same OLEU leaf. Symbols = temperatures measured by infrared
thermography; lines = model of leaf thermal dynamics fitted to the data.
In this example, the time constants for cooling (τ ) calculated
from the fitted models were 9.79 and 10.94 seconds for the bald and
hairy patches, respectively. Note: the symbols are plotted with a very
small size so as not to obscure the close match between the fitted model
and the data.
