The function pyl4c.data.fixtures.restore_bplut() returns a dictionary representation of the Biome Properties Lookup Table (BPLUT) that looks something like:
"vpd": array([[...],
[...]])
...
For parameters that define the slope of ramp functions on fields like VPD, minimum temperature, etc. This format (above) uses a multi-dimensional numpy.ndarray where the first axis enumerates each parameter of the ramp function.
Now, for compatibility with newer libraries and applications, a flatter format is proposed:
{
"vpd0": [...],
"vpd1": [...],
...
Where [...] could be a 1D numpy.ndarray or a flat sequence.
