Question about Ionospheric correction with stackSentinel.py

[SofiViotto]

Hello!

I was wondering if anyone can answer this question for me. I have been running the ionospheric correction implementation for the sentinel stack application. At the end, the final product is a time series of the ionospheric delay in radians, which can be converted to offset (please correct me if I am wrong). My question is the following: is the time series I get at the end a two-way or single-way ionospheric delay? I suspect it is the double delay but I would like to confirm it.

Thanks in advance!

Best,

Sofia

It is two-way ionosphere.
