Load an experimental spectrum

Load an experimental spectrum stored as .spec (with units and metadata) using load_spec() (we could also have used plot_spec() directly !)

See more loading and post-processing functions on the Spectrum page.

my_file = getTestFile("CO2_measured_spectrum_4-5um.spec")  # for the example here

s = load_spec(my_file)
s.plot()

# Print all metadata:
print(s)

# Or retrieve an information :
print(s.crop(4160, 4200, "nm").max())
