# Asteroid families - resonance crossing analysis

[ back to Asteroid families main page ]
The detailed *a*(*t*) figures are available for surroundings
of the following mean motion (or 3-body) resonances:
J13/5 (3J-1S-1),
J9/4,
J23/10 (5J-1S-2),
J11/5 (3J-2S-1) and
J13/6.

The data files (*.out) contain information about
(i) time of the entry into the resonance region for each test particle
(the fourth column) and (ii) time, when TPs leave the resonance
(the fifth column). (Zeroes mean that (i) TP did not reach the resonance
or (ii) it stayed trapped for the rest of integration time.)

Number of particles crossing particular resonances (and other TPs in runs),
mean and median times of arrival to the resonance and crossing:

run |
resonance |
always outside |
initially resonant |
still resonant after end |
crossing particles |
in one (preferred) direction and `e`_{out} < 0.5 |
mean arrival and crossing time [Myr] |
median times [Myr] |

2DO: compare the crossing times to (expected initial) analytical drifts (for each TP individually!).

## Eos - J9/4 and 5J-1S-2 (or J23/10?)

### 5J-1S-2 (or J23/10?)

## Themis - J11/5 (plus 3J-2S-1?) and J13/6

## J13/6
