-Having to fit the mutual and loop inductance is one of the weaknesses of our method. In the linear regime of the dc-SQUID extracting the mutual inductance should be trivial. The loop inductance however is determined by the periodicity in the data. Whilst possible to compare the loop inductance to a simulated value, a factor two difference already changes a $2\pi$-periodic CPR to a $4\pi$-periodic current-phase relation. To overcome this, a reference loop without any junction could be added.

Alternatively, since the loop inductance also in part determines the amplitude of the junctions critical current, it is possible to later cut the junction loop and measure the critical current of just the junction.
 
 Previously we thought the steep curve was caused by a multivalued measurements. However, with these new results we think we wrong mainly because we see such a gradual transition.
