Welcom to the WebSky [CII] Mocks simulation product archive!

In this directory, you will find the WebSky tomographic [CII] intensity
mocks and corresponding Peak Patch dark matter halo catalogues for each of
the cases used in arXiv:2510.18312.

The data from each run is contained in a directory. Runs that are 
primordially Gaussian can be found in the `Gauss/' directory, and runs with
primordial intermittent non-Gaussianity can be found in the `PING/'
directory.

Primordially Gaussian runs use Planck 2018 parameters (see arXiv:1807.06209
"Planck 2018 results. VI Cosmological Parameters", Table 2, column
TT,TE,EE+lowE+lensing) unless a parameter is otherwise specified in the run
directory. PING runs have amplification factor Q, characteristic scale
factor a_e, effective mass term m_lambda and chi field mass m_chi as
specified in the subdirectory name.

Within each run, you will find the following files:

  Peak Patch Parameter Files

  - `params_7.5Gpc.txt' : the full set of Peak Patch initial conditions are
        for the run centred at comoving distance 7.5 Gpc (spanning
        redshifts 3.5 <~ z <~ 5).

  - `params_8.6Gpc.txt' : the full set of Peak Patch initial conditions are
        for the run centred at comoving distance 8.6 Gpc (spanning
        redshifts 5 <~ z <~ 8).

WebSky [CII] Intensity cubes are in Jy/srad. Intensity cubes of the form
`cii_*_7.5Gpc.pnz' have shape (1214,1214,41) and intensity cubes of the form
`cii_*_8.6Gpc.npz' have shape (1214,1214,34). The first two dimensions are RA
and dec in degrees which have symmetric bin edges:

    RAdec_bins = np.linspace( -3.43780731, 3.43780731, 1215 )

The third dimension is frequency in Hz. Intensity cubes of the form
`cii_*_7.5Gpc.npz' have frequency bins

    nu_bins = np.arange( 308.06, 426.00, 2.8 )

and those of the form `cii_*_8600.npz' have frequency bins

    nu_bins = np.arange( 210.98, 309.00, 2.8 )
