Hey folks! I am very new to IDL. Here is my problem: I have three different arrays shown below
Array one:
index # Latitude longitude Orbit # Ls Local time
0 33.4829 144.685 29074.0 185.281 0.715993
2 36.3315 91.0626 29076.0 185.371 0.719348
3 37.0565 64.0919 29077.0 185.415 0.720421
4 33.3151 35.5232 29078.0 185.459 0.716017

9 37.7809 105.764 29082.0 185.651 0.236322
10 34.8291 76.3341 29083.0 185.696 0.231116
11 36.2353 50.1601 29084.0 185.740 0.233895
12 38.3637 24.1150 29085.0 185.785 0.236893
13 35.8291 -4.69733 29086.0 185.830 0.233335
14 35.6629 -32.0563 29087.0 185.874 0.233214
16 32.8421 -61.2955 29088.0 185.920 0.228516
17 37.6395 -85.4017 29089.0 185.964 0.236161
What I need to is to organize the data so that the the orbits are are in a ascending order in groups of three. if there is not a match then I need it to skip the row for all three. Here is an example:
Array 1 orbit # Array 2 orbit # Array 3 orbit # Array 1 index # Array 2index # 3idx#
29074.0 29075.0 29076.0 0 2 3
I was thinking of doing something like this.
for j = 0, n_elements-1 do begin
orb_num=array_1[j]
if array_2(3,*,*,*,*,*) eq orb_num+1 and array_3(3,*,*,*,*,*)+2 then begin
print, array_1(3,*,*,*,*,*)[j] , array_2(3,*,*,*,*,*)[j], array_3(3,*,*,*,*,*), array_1(0,*,*,*,*,*), array_2(0,*,*,*,*,*), array_3(0,*,*,*,*,*)
Does anyone know if this idea would work? any suggestions?
