review of windspeed.py

No description provided.

The first commint concerns cases where sigma0 <=0 or sigma0 == NaN (on the left side of the image here)

before commit :

after commit :

In this case in the previous version, xsarsea was replacing copol by ancillary and used ancillary for dualpol inversion. Now inversion returns NaN

[vincelhx]

the second change concerns the wind direction output from inversion. The returned angle was false before these commits. Now, the return complex can be used.

use this formula to get wind direction in meteorological convention :
90 - (np.angle(-np.conj(wind_xsarsea), deg=True)) + xr_dataset.ground_heading) % 360

[vincelhx]

Lut being symetrical, i chose phi or -phi by taking the closest angle from ancillary.

[vincelhx]

i also updated documentation. make html is ok @agrouaze

[vincelhx]

added cmod7 gmf

[agrouaze]

just the notebook windspeed_inversion to check .

[agrouaze]

Can you check this notebook is output free?

[vincelhx]

done

[agrouaze]

name of the script other_luts.py is a bit weird but you are the one that play the more with this lib.

[vincelhx]

changed!
