It adds (or subtracts) 2pi to the phase difference between the unkown and the standard as some times it does not eztrapolate to zero as 2k*delta r term should.

Dear all,

i have a question to the Log-Ratio/Phase-Differnce Analysis in Athena. What 
means the parameter 2pi jump?
I did not find any help file for the ratio method.

Best regards
