| Instruction | Description | |
|
|
||
| 1 | fid=set_fiducial(cosmo_in={omega_m:0.31}) | Set fiducial parameters, choosing a non-default value of the parameter Ωm |
| 2 | cosmo=mk_cosmo(fid) | Compute basic cosmological quantities (e.g., distance measures, power spectrum) |
| 3 | plt_cosmo,cosmo,“z”, “da” | Plot angular-diameter distance DA(z) as a function of redshift z |
| 4 | plt_pk,cosmo,z=0 | Plot non-linear matter power spectrum P(k) at z = 0 |
|
|
||
| 5 | sv=mk_survey(fid,“sv1”) | Read survey parameters for the preset DUNE experiment |
| 6 | cl=mk_cl_tomo(fid,cosmo,sv) | Compute cosmic shear power spectrum Cl |
| 7 | cl_cov=mk_cl_cov_tomo(fid,cl,sv) | Compute cosmic shear power spectrum errors |
| 8 | plt_cl,cl,[0,0],cl_cov,/errors | Plot shear power spectrum and associated errors |
|
