This repository contains the modified CLASS code that we have used to run our analysis for our tomographic coupled dark energy (CDE) model (see Goh, Gómez-Valent, Pettorino and Kilbinger (2022)). It is an extension of the one employed for a constant coupling strength in Gómez-Valent, Pettorino and Amendola (2020) and Gómez-Valent, Zheng, Amendola, Wetterich and Pettorino (2022).

We have included the version with a 3-bin parameterisation, with bin edges z={0,100,1000}.

We have also included a notebook to reproduce Figures 2, 3 and 12 of our paper.

All the changes and new parts of code implemented in class_CDE are duly indicated with the text /* NEW */.

We describe what are the input parameters employed by class_CDE in the CDE.ini file.
