I have WA. But I just found all maximum values in 1..m, 2..m+1, 3..m+2
etc. And I thought that it is what I must to do.
But what does that mean: "If the intensity was low within the last 6
hours the magnetic field was regarded to be quiet; the children were
let outdoors and played all the prescript time. Otherwise new peaks
were probable and the children spent their time indoors."
What should I do with 6 hours? Or maybe it is just an example?

Don't mind. it 's just the background, It is nothing with the problem.
