Thanks for your reply! I guess I should have made my question a bit more lucid; I had the data of a two-tone spectroscopic measurement (which yielded the avoided crossing plot of a variable frequency transmon with a 3D cavity). This was all I had at the moment, from which I had to find Ec, Ej...

Hi everyone, I’ve performed microwave measurements on a 3D transmon and want to find the E_J value of the qubit. I’ve tried searching through many papers, particularly Koch et al, about how to do this, but I am stumped. Could someone please help me out? Thanks in advance.
