CAMB Error/Halofit error on a RSD and CMBLens run

Post by Luke Hart » July 28 2015

I'm attempting to run the LSS survey for the RSD dataset and also for the CMB lensing dataset on their own (in 2 separate runs) to try and isolate contributions to an LSS plot I've created.

However, in running the redshift space distortion data on its own and the PLANCK lensing on their own; I've encountered a couple of errors pointing to CAMB specifically and in the RSD its pointing to halofit (the non linear dark matter fit F90 porgram) whilst the CMB lensing error is pointing to 'failing to find end of recombination'

Does this mean that neither of these datasets can converge?
Or have I made a fatal error in setting up these runs?

For CMB lensing, are you using batch2/lensonly.ini? You need to fix unconstrained parameters like tau.
