syn_obs.py

Can you run syn_obs.py? the init file has the wavelength information but it instantly crashes with

In [2]: mod = hazel.Model('conf_synobs.ini') Adding spectral region spec1

• Setting all weights to 1

  UnboundLocalError Traceback (most recent call last)

Fixed.

Thank you. With the latest upgrades to the code, the "Basic Usage" example does not work anymore. it complains like this:

Exception                                 Traceback (most recent call last)
<ipython-input-1-a198a398a488> in <module>()
      2 import matplotlib.pyplot as plt
      3 mod = hazel.Model(working_mode='synthesis')

      5 mod.add_chromosphere({'Name': 'ch1', 'Spectral region': 'spec1', 'Height': 3.0, 'Line': '10830', 'Wavelength': [10826, 10833]})
      6 mod.setup()

    309         if (value['los'] is None):
    310             if (self.working_mode == 'synthesis'):
--> 311                 raise Exception("You need to provide the LOS for spectral region {0}".format(value['name']))
    312             los = None
    313         else:

Exception: You need to provide the LOS for spectral region spec1

adding 'LOS': [0.0,0.0,90.0], 'Boundary condition': [1.0,0.0,0.0,0.0] to the line of add_spectral solves the problem.

Thanks! I forgot to update this part of the docs. Done.
