File Toliou+_2021_MNRAS.dat contains the probabilities of past 
minimim perihelion distances achieved by NEAs and the corresponing
dwell times, described in:

Toliou, Granvik, Tsirvoulis (2021), Minimum perihelion distances and
associated dwell times for near-Earth asteroids, accepted for publication in MNRAS. 


The file contains a grid of 458,170 cells in a,e,i,H, with ranges 
0<a<4.2 au
0<e<1
0<i<180 deg
15<H<25 
and provides the probability that an asteroid with given a,e,i,H has had, during its past evolution, q
below 26 threshold values (q_s) in the range 0.05<=q_s<=1.3 au and, in addition, the time it has spent having q
in a range defined by two subseqent q_s values (dwell time). The file is organized in the following way:

>>>Columns 1-4:
1) semimajor axis [au]
2) eccentricity
3) inclination [deg]
4) absolute magnitude



>>>Columns 5-30:
5) minimum q probabilities (P_qs) for q_s<=0.05 au
6) -//- for q_s<=0.1 au
7) -//- for q_s=<0.15 au
.

30) -//- for q_s<1.3 au



>>>Columns 31-56:
31) median dwell times (T_qs) for 0<q<=0.05 au 
32) -//- for 0.05<q<=0.1 au

>>>Columns 57-82:
