Content

Below, you can find the following ZIP folders:

• Figures: PDF files of all figures used in the associated paper (arXiv:2602.06115).
• Plotting code, consisting of the main Jupyter notebook file and 3 python helper scripts for the reading in of the various MCMC and nested sampling chains.
• Snapshot of the development branch of anesthetic used for post-processing and plotting.
• 5 ZIP folders with the MCMC and nested sampling chains: one folder for each cosmology (LCDM, LCDM+Mnu, LCDM+OmegaK, wCDM, w0waCDM).

Plotting code 

The python helper scripts are only there to read in the MCMC and nested sampling chains into NestedResults objects called for example s_t4eLbHl4D2PP_L0, where s_ stands for "samples", t4eLbHl4D2PP is a string of 6 letter pairs standing for:

1. low multipole TT likelihood: __ (none), t3 (Commander), t4 (also Commander),
2. low multipole EE likelihood: __, e3 (SimAll), eL (Lollipop),
3. high multipole TTTEEE likelihood: __, P3 (Plik), CS (CamSpec PR4), bH (binned Hillipop),
4. BAO likelihood: 12 (SDSS DR12), 16 (SDSS DR16), D2 (DESI DR2),
5. SN likelihood: D5 (DES year 5), PP (Pantheon Plus), U3 (Union 3), also HF and HR for H0 likliood from Freedman or Riess respectively,

and finally the ending _L0 indicates the cosmological models:

• L0: LCDM,
• d3: LCDM+Mnu (with 3 degenerate neutrino masses),
• OK: LCDM+OmegaK (with non-zero spatial curvature),
• w0: wCDM (with constant dark energy),
• wa: w0waCDM (with dynamic dark energy).

MCMC and nested sampling chains

The sampling chains are separated by cosmological model into 5 ZIP folders. The fileroot for each chains consists of:

• A prefix (separated by a double underscore __): MCMC, CPPC3d1000, or CPPC5d2000, corresponding to an MCMC chain, or a nested sampling chain with either nrepeat=3d, nlive=1000 or nrepeat=5d, nlive=2000, respectively.
• A suffix (also separated by a double underscore __) signals the cosmological model: LCDM, LCDM_Mnu-d3, LCDM_OmegaK, wCDM, w0waCDM.
• The middle section identifies the combination of liklihoods, separated by a single underscore _:
  • lowlTT-PR3: Planck low multipole Commander TT likelihood (this is the PLA version).
  • lowlTT-PR4: Planck low multipole Commander TT likelihood (this is the python re-write in Cobaya).
  • lowlEE-PR3: Planck low multipole PR3 SimAll EE likelihood.
  • lowlEE-LP: Planck low multipole PR4 Lollipop EE likelihood.
  • TTTEEE-PR3: Planck high multipole PR3 Plik TTTEEE likelihood.
  • TTTEEE-CS4: Planck high multipole PR4 CamSpec TTTEEE likelihood.
  • TTTEEE-HPbin: Planck high multipole PR4 binned Hillipop TTTEEE likelihood.
  • lensing-PR3: Planck PR3 CMB lensing likelihood.
  • lensing-PR4: Planck PR4 CMB lensing likelihood. 
  • BAO-SDSS12: SDSS DR12 BAO likelihood.
  • BAO-SDSS16: SDSS DR16 BAO likelihood.
  • BAO-DESI2: DESI DR2 BAO likelihood.
  • SN-DESy5: DES year 5 SN likelihood.
  • SN-PP: Pantheon Plus SN likelihood.
  • SN-U3: Union 3 SN likelihood.
  • H0-F20: TRGB distance ladder H0 likelihood from Freedman et al. 2020.
  • H0-R20: Cepehid varibables distance ladder H0 likelihood from Riess et al. 2020.
