Set A
Matter power spectra from 12288 N-body simulations with 656 Mpc h-1 box-length and 2563 particles of a LCDM model with parameters: h=0.72, Ωmh2=0.1334, Ωbh2=0.02258, ns=0.963, σ8=0.801.
The spectra have been computed using the code POWERGRID (Prunet et al. 2008) and corrected for mass resolution errors as described in Blot et al. (2015). Data files are two columns ascii format: k, P(k). For each redshift the tarball file containing the 12288 spectra can be downloaded from the links below:
| z | 0.00 | 0.10 | 0.30 | 0.50 | 0.70 | 1.00 | 1.50 | 2.00 | 105.0 |
Set A (uncorrected)
Matter power spectra as in Set A without correction for mass resolution errors.
| z | 0.00 | 0.10 | 0.30 | 0.50 | 0.70 | 1.00 | 1.50 | 2.00 | 105.0 |
Set B
Matter power spectra from 96 N-body simulations with 656 Mpc h-1 box-length and 10243 particles for the same cosmological model of Set A. Files are in the same format as those of Set A. For each redshift the tarball file containing the 96 spectra can be downloaded from the links below:
| z | 0.00 | 0.10 | 0.30 | 0.50 | 0.70 | 1.00 | 1.50 | 2.00 | 105.0 |
File names are in the form powermcorrected_XXX.tar.gz where XXX is the value of the scale factor at the snapshot redshift.
