Compilation Parameterised-Post-Friedmann (PPF)

Post by Dournac Fabien » March 08 2022

Hello,

I was working up to now with CAMB-0.1.7 wiht Parameterised-Post-Friedmann (PPF) with (w0,wa) parameters : for this I had to compile CAMB-0.1.7 with the following command :

Code: Select all

$ make EQUATIONS=equations_ppf 
Now I am using CAMB-1.3.5 and I wonder if a simple

Code: Select all

make
is enough to get the same specifications than with CAMB-0.1.7.

Indeed, if I add this line in CAMB-1.3.5 params.ini :

Code: Select all

#Dark energy can be "fluid" (constant w), or "PPF" (allowing wa, and w=-1 crossing)
dark_energy_model  = PPF
a simple

Code: Select all

make
just could do the same job, no ?

Regards

PPF and fluid are both compiled by default in the latest version yes, you can just pip install.

ok, thanks.

So, the following line in recent versions of CAMB is necessary to avoid "make EQUATIONS=equations_ppf

Code: Select all

dark_energy_model  = PPF
??
