### First value for k is not always the same

Posted: June 17 2019
Hello,

I am generating matter power spectrum with different parameters ( (using CAMB-1.0.4).

At the total, I have 300 output files test_matterpower*.dat.

and What I don't understand is that the first value "k/h" extract from these files is not always the same.

For a majoity of files, I get for the first value :

Code: Select all

k/h=0.527815E-05

but for a few files, I get a different starting value : how to explain this ? Is it normal ?

How to force it to make all the same first values for every output file ?

Thanks

You can set transfer_interp_matterpower=T, otherwise it uses the actual internal sampling.
