We also find that allowing for a DDE background both weakens constraints and pushes the posterior to higher masses allowing for a ~2 sigma constraint in our baseline data combination with Planck PR4.

We find that the consistent addition of low-z data (KiDS/BOSS/CMB lensing) pushes DDE constraints back towards a cosmological constant. We do not include Supernovae in this analysis (but we are currently working on this!)
