The 3 IDL save files in this directory are snapshots of the fields at 3 time
instances from the rising flux tube simulation case LNT described in
Fan (2008, ApJ, 676, 680). The simulated velocity fields are used in
Birch et al. (2010, ApJ, 723, L190) to estimate helioseismic travel
time perturbations that can be produced due to the flow associated
with the rising flux tubes.
Below is a description of the data after restored in IDL, using idlsave_018.dat
as an example:
