totalStrListDdict

A dictionary containing all circuits for all sine and cosine experiments for alpha, epsilon, and theta. The keys of the returned dictionary are:

• ‘alpha’,’cos’ : List of circuits for cosine experiments used to determine alpha.

• ‘alpha’,’sin’ : List of circuits for sine experiments used to determine alpha.

• ‘epsilon’,’cos’List of circuits for cosine experiments used to

determine epsilon.

• ‘epsilon’,’sin’ : List of circuits for sine experiments used to determine epsilon.

• ‘theta’,’cos’ : List of circuits for cosine experiments used to determine theta.

• ‘theta’,’sin’ : List of circuits for sine experiments used to determine theta.

• ‘totalStrList’ : All above circuits combined into one list; duplicates removed.
