This directory contains an index.html file with links to the run directories for Runs A1-C4u of Table 1 and idl plotting routines with secondary data for the 14 figures of the paper "Isochrones in primordial magnetic field evolution" by A. Brandenburg, M. Cielo, O. Iarygina, & F. Vazza. Each run directory contains the input files (start.in, run.in, print.in, etc), the files src/Makefile.local and src/cparam.local with the relevant compile information, and a data directory with time_series.dat files and data for energy spectra (power_kin.dat, power_mag.dat, powerhel_mag.dat, and powerhel_kin.dat), and jobid.dat files with code revision numbers and compile times. The correlation length (xiMag) and magnetic energy (EMag), along with other parameters, are listed in kpm.txt. A readily browsable URL with the same information is available on https://norlx65.nordita.org/~brandenb/projects/Isochrones/. If anything turns out to be incomplete, or you want data in some other format, please email brandenb@nordita.org.
