It seems that both likelihoods in 5_COSMOLOGY/cosmosis_likelihoods use the same covariance matrix (Pantheon+SH0ES_STAT+SYS.cov). I believe that this covariance is the sum of SNIa and Cepheid data cova…

There's been a few people stacking YI models and the results are rather good. Unfortunately they are slower than a 70b especially when using their extended context.
Can anything be done? Is because…

Hello! I've been investigating something that was initially flagged by Noah (@nweaverd), where the posterior reported by the importance sampler and polychord sampler slightly differ in some cases even…

The initial plan is to use CosmoSIS and turn off any CMB, etc, priors so we can directly compare with the fixed input parameters.

I have noticed that there is no way currently to use the clustering statistics in `scale_cuts.py`, even though the `twopoint_wrapper.py` and `twopoint.py` that are used allow for the `w`, `Pnn` and co…

List of things to check:
1. make sure example runs and produce chain
2. go through config file to understand what is what, also for output files
3. make sure we can submit an actual batch job
4. c…

# Infusing IA in SkySim5000
This sprint will infuse IA in mock lensing catalogues based on SkySim5000 (not the official one) and assign intrinsic alignment models based on the projected tidal field…

On Cosmosis, we used some equations we found online to calculate the Color Temperature, and subsequently the RGB color, from the B-V Color.
You can find our ruby implementation here:

In taking a closer look at some chains I ran a couple weeks ago, I'm seeing some odd behavior that may have to do with updates to how the campaign runs handle variables. This behavior has appeared on …

This requires functionality to draw samples of data vectors from the likelihood and passing them back to the sampling framework.
The ability to draw samples from the likelihood is useful in other c…
