Computers and software • CAMB: GR correction?

Hi,

I'm trying to calculate the GR correction for an N-body simulation as defined below.

[math] k^2 \gamma_{GR} = -\left(\partial_\tau + \frac{\dot{a}}{a}\right)\dot{H}_T + 8\pi G a^2 \Sigma
(https://arxiv.org/pdf/1811.00904.pdf)

Is there a general routine to calculate such a quantity in the CAMB code?

Thanks for any help!
