Python notebook for H0 inference using H0LiCOW collaboration's 6-lens distance measurements. The python notebook is also available here:
https://github.com/shsuyu/H0LiCOW-public/tree/master/H0_inference_code
The posterior distributions of the time-delay distances and angular diameter distances for five of the six lens systems can be downloaded here:
https://github.com/shsuyu/H0LiCOW-public/tree/master/h0licow_distance_chains
The remaining lens (B1608+656) has an analytical fit to the PDF.
If you make use of the distance measurements (time-delay distance and/or lens angular diameter distance) to the 6 lens systems from H0LiCOW, please cite the relevant publications:
- Suyu et al. 2010 (B1608+656 time-delay distance fit)
- Jee et al. 2019 (B1608+656 angular diameter distance fit)
- Chen et al. 2019, Wong et al. 2017 (HE0435-1223 distance posterior)
- Birrer et al. 2019 (J1206+4332 distance posterior)

- Rusu et al. 2019 (WFI2033-4723 distance posterior)
- Wong et al. 2019 (combined inference)
The H0 inference from these posteriors can be obtained following the python notebook. The cosmological parameter chains from running the python notebook are available here:
