# This notebook demonstrates basic usage of the firefly_client API, overlay_footprints, which overlays the footprint described in image pixel of JSON format on the fits image 

# ## Setup

# Imports for Python 2/3 compatibility

# In[ ]:


from __future__ import print_function, division, absolute_import


# Imports for firefly_client

# In[ ]:

# In this example we use the local Firefly server.

# Instantiate `FireflyClient`.

# Open a browser to the firefly server in a new tab. The browser open only works when running the notebook locally, otherwise a link is displayed.
