| + | |||
| + | - The sound speed in the code units is 0.25. | ||
| + | - Slow shocks are in blue. | ||
| + | - Fast shocks are red. | ||
| + | - Rotational discontinuities are green. | ||
| + | - Parker sheets are cyan. | ||

| + | Distributions are no longer normalised, the numbers on the y axis are therefore numbers of scans. I kept only the best identifications we have (purest wave decompositions). It just makes distributions cleaner and analysis simpler. | ||

| I am actually doing it, but it's a lot of data and my internet connection is not very fast here... I'll tell you if is bimodal too. | I am actually doing it, but it's a lot of data and my internet connection is not very fast here... I'll tell you if is bimodal too. | ||

| + | And for slow shocks, here are two sets of identical shock velocities (vs=1.2*cs*cos(theta) and vs=1.8*cs*cos(theta)) but on the left we have a "weak" magnetic field such that vA = 2*cs and on the right a "strong" field such that vA = 3*cs. | ||

| + | |||
| + | So as usual higher shock velocities lead to higher shear velocities. But for a fixed shock velocity lower magnetic field strength gives higher shear velocity. | ||
