### Combining two CMB lensing likelihoods

Posted:

**May 21 2019**Hi Antony and all,

I'm trying to combine two CMB lensing likelihoods, the one from Planck 2018 and another one based on the Gaussian likelihood (including linear corrections) in CMBlikes.f90.

To this end, I simply point to the two likelihoods in my CosmoMC parameter files, i.e.

However, the second dataset is not included when I run the sampler (in fact, it doesn't appear in the .likelihoods file produced during the run).

I'm assuming the cmb_dataset[lensing] instruction is not read twice but I couldn't exactly pinpoint the source of the problem.

Any feedback would be greatly appreciated!

Cheers,

Code: Select all

```
DEFAULT(CosmoMC/batch3/lensing.ini)
DEFAULT(CosmoMC/batch3/my_very_own_lensing.ini)
```
