Ok that's brilliant thanks.

But what if the initial wavelengths sometimes varied, so you might get:

4862 x(1) y(1) z(1)
4958 x(1) y(1) z(1)
5007 x(1) y(1) z(1)
4860 x(2) y(2) z(2)
4959 x(2) y(2) z(2)
5007 x(2) y(2) z(2)
4861 x(3) y(3) z(3)
4959 x(3) y(3) z(3)
5008 x(3) y(3) z(3)

for example. So you couldn't match the lines based on the homogeneity of the value in $1, and therefore had to on the line number. Could you do it this way?
