# Generating a Telluric Model with TelFit¶

Making a telluric model used to be hard. With TelFit, it is just a few lines of code.

from telfit import Modeler

# Set the start and end wavelength, in nm
wavestart = 500.0
waveend = 900.0

# Make the model
modeler = Modeler()
model = modeler.MakeModel(humidity=50.0,
lowfreq=1e7/waveend,
highfreq=1e7/wavestart)
