there is a function in

Code: Select all

`camb.model`

Code: Select all

`set_for_lmax(lmax, max_eta_k=None, lens_potential_accuracy=0, lens_margin=150, k_eta_fac=2.5, lens_k_eta_reference=18000.0)[source]`

Code: Select all

```
import camb
pars.set_for_lmax(512, lens_potential_accuracy=0)
#get dictionary of CAMB power spectra
powers = results.get_cmb_power_spectra(pars)
totCL=powers['total']
print totCL.shape
```

(551, 4)

That's unexpected. Shouldn't the length of the array for power spectra by 513, as that's the lmax value?

What's going on here? Was that in the original CAMB Fortran code?
