Hi @JosephKarpinski, thanks for reporting this. While I was able to run this notebook without issue, I see that there is a deprecation warning for setting an array element with a sequence for the rot variable:

DeprecationWarning: setting an array element with a sequence. This was supported in some cases where the elements are arrays with a single element. For example np.array([1, np.array([2])], dtype=int). In the future this will raise the same ValueError as np.array([1, [2]], dtype=int). rot = np.array(rot,np.float64).flatten()

Try replacing rot=(f4['ra'],f4['dec'],0) with rot=(f4['ra'].array[0],f4['dec'].array[0],0)

Let me know if this works for you, and I will update the notebook accordingly.

That worked. Thank you!
