Run directories:

  • Figs. 1+2: Willis
  • Fig. 4: NNT
  • Fig. 5: TTT
  • Fig. 7: uses k1om.dat from paper_idl, computed in, e.g.,C32o1 for ω=1.
  • Fig. 8: uses om0k.dat from paper_idl, computed in, e.g.,T32k14a for k=0.25.
  • Fig. 9: uses alpetaz.sav from T32a.
  • Fig. 10: uses k1om0eta.dat from paper_idl, computed in, e.g.,T32eta015a for η=0.15.
  • Fig. 11: uses pxyaver.pro from run_idl in T32zNNTeta0133a.
  • Fig. 11: uses pxyaver.pro from run_idl in NNT17x17x32a_k1_rot.
  • Fig. 12: uses alpetaz.sav in palpeta_T48TTTr.pro from run_idl for panels (a) and (b).
  • Fig. 13: uses alpha_tensor_z.dat and eta_tensor_z.dat from in NNT17x17x32a_k1_rot.
  • Fig. 14: uses alpha_tensor_z.dat and eta_tensor_z.dat from in TTT25x25x48a_k1_cor.
  • Table 1: ABC, Roberts, Willis*, Willis, NNT, TTT.
  • Table 2: mft_NNTr32a for NNT and mft_TTT48a for TTT.

    The run directories contain unformatted data files uu.dat for the flow fields. They can be read directly with the Pencil Code and with the corresponding idl routines that are in the directory run_idl.
