I would like to have my data in a format so that I can create a contour plot.

My data is in a file with a format, where there may be multiple fields

field = 1

1a	0
2a	0
3a	5
4a	5
5a	5
6a	5
7a	5
8a	5
9a	0
10a	0
1b	0
2b	0
3b	5
4b	5
5b	5
6b	5
7b	5
8b	5
9b	0
10b	0

field = 2

1a	0
2a	0
3a	0
4a	4
5a	4
6a	4
7a	4
8a	0
9a	0
10a	0
1b	0
2b	0
3b	0
4b	4
5b	4
6b	4
7b	4
8b	0
9b	0
10b	0

field = 3

1a	0
2a	0
3a	0
4a	0
5a	3
6a	3
7a	0
8a	0
9a	0
10a	0
1b	0
2b	0
3b	0
4b	0
5b	3
6b	3
7b	0
8b	0
9b	0
10b	0

I could possibly have many of these that I will add together and
normalize to one.
Also, there are 60 a and b blocks, the middle 40 are 0.5 times the
width of the outer 20.

I thought about filling an array, but there is not a one to one symmetry.

I cannot seem to get my head around this. Can anybody help me get started?
