Array handling issue with plotter.plot_atmosphere_model() with RBF interpolation

[cylammarco]

To reproduce the plots:

from WDPhotTools import plotter 
from matplotlib import pyplot as plt

plt.ion()
plotter.plot_atmosphere_model(interpolator='CT') 
plotter.plot_atmosphere_model(interpolator='RBF')

>>>
>>> y_itp(7.5, 1500)
