Problem when running KV450 on wCDM #192

Closed DinorahBarbosa closed 1 year ago

DinorahBarbosa commented 3 years ago

Hi all,

I have been trying to create chains for the wCDM model on MP with the following datasets: Planck2018+Pantheon+eBOSS+KV450. However, they appear to diverge when I include the KV450. I have no clue what I am doing wrong. I've included my .param as a .txt file below so you can take a look to see if there's any problems.

Bests,

w0 is a very poorly constrained parameter. Try setting a wider initial sigma (~0.1-0.5) and pass a Planck LCDM covmat.

Best, Thejs
