Dear Kwant developers, I would like to ask the following questions about mode wave functions. 1. The mode wave functions can be obtained in three ways: using the smatrix.lead_info, using finalised_lead.mode.wavefunction and using the physics.Progatingmodes. Are they the same? To find the modes used to obtain the s matrix, we should use the modes of matrix.lead_info. Am I correct? 2. I want to find the sites of the mode wave functions obtained from s matrix. Is it correct to use finalised_system.leads[n].sites as mentioned in one of the discussions. I print out finalised_system.leads[n].sites, which is a long list of

Site(kwant.lattice.Monatomic([[1.7320508075688772, 0.0], [0.0, 1.0]], [0.2886751345948129, 0.0], '1', 1), array([0, 0])) Could you please help me to find out what the information represents? 3. Is it correct to use finalised_system.leads to find the sites information for the mode wave function obtained from the s matrix?

I should be grateful, if you could help me in this regard. Thank you in advance. Your sincerely, KS
