README::: These files are vertical velocity, time-averaged vertical magnetic field, and time-averaged continuum intensity from the magnetoconvection simulation of Matthias Rempel and colleagues. In all cases, we have applied an MTF=exp(-(W*k)^2) with W=0.7 Mm and k in units of rad/Mm and then binned the data 4x4 in (x,y). The horizontal grid spacing in the final result is 4x96 km. The cadence is one minute. There was a restart of the simulation, with small changes in the radiative transfer and the div B cleaner, at minute 640. The file dt_mean_maps.tar.gz contains FITS files of the set of maps of the mean travel-time shifts determined from the simulation by helioseismic holography and time-distance helioseismology. Examples and details of these maps are reported by Braun et al. 2011 ApJ, 744, 77. For questions about the simulation contact Matthias Rempel (rempel@ucar.edu).
