Outdated notebooks

[maxnoe]

While replacing the gamma test file with the newer, lstprod2 version, I found that some notebooks no longer work with current lstchain and its dependencies:

• notebooks/disp.ipynb

  TypeError: CameraCalibrator.__init__() missing 1 required positional argument: 'subarray'

• notebooks/example_container.ipynb

  TypeError: CameraCalibrator.__init__() missing 1 required positional argument: 'subarray'

• notebooks/lstchain.ipynb

  ImportError                               Traceback (most recent call last)
  Cell In[5], line 3
        1 # Take a look at the parameters extracted from the simtelarray file:
  ----> 3 from lstchain.tests.test_lstchain import dl1_file, dl1_params_lstcam_key
        5 data = pd.read_hdf(output_filename, key=dl1_params_lstcam_key)
        6 print(data.keys())
  
      ImportError: cannot import name 'dl1_file' from 'lstchain.tests.test_lstchain' ([/home/mnoethe/Uni/LST/cta-lstchain/lstchain/tests/test_lstchain.py](http://localhost:8888/lab/tree/notebooks/lstchain/tests/test_lstchain.py))
  

• notebooks/calculate_sensitivity_eventio.ipynb uses pyhessio

• notebooks/step_by_step_dl0_to_dl1.ipynb uses pyhessio and:

  ---------------------------------------------------------------------------

related #1091, I think we should make the effort to clean and update the notebooks and try to CI test them using test data
