Niether of them worked; the problem was it seemed to pick random points not the peaks (I plotted them using GMT).
Instead of accepting defeat can I trouble you for a little explanation, if I understood the logic a little better I think I could tweak it. I am still new at awk but my professor loves it, and the more I use it the more I realize how powerful it actually is.
This is the part I don't quite understand. What exactly does NR == 1 accomplish? Your setting the number of rows equal to one? does a ';' seperate commands? So you set last equal to column 2, lost_row equal to column one.
Why do your run a getline? I looked it up and it is defined as:
getline - returns 1 if it finds a record, and 0 if the end of the file is encountered
Anyways I get the feeling that $1 and $2 are now rows above and below not columns?
This part logically makes sense, and this is what I am trying to accomplish.

IGAWK(1) Utility Commands IGAWK(1)NAME
igawk - gawk with include files
SYNOPSIS
igawk [ all gawk options ] -f program-file [ -- ] file ...
igawk [ all gawk options ] [ -- ] program-text file ...
DESCRIPTION
Igawk is a simple shell script that adds the ability to have ``include files'' to gawk(1).
AWK programs for igawk are the same as for gawk, except that, in addition, you may have lines like
@include getopt.awk
in your program to include the file getopt.awk from either the current directory or one of the other directories in the search path.
OPTIONS
See gawk(1) for a full description of the AWK language and the options that gawk supports.
EXAMPLES
cat << EOF > test.awk
@include getopt.awk
BEGIN {
while (getopt(ARGC, ARGV, "am:q") != -1)
...
}
EOF
igawk -f test.awk
