You could use awk to print only the second column, i.e., the second by white space separated word of each line, when it exists in this record. Then it would also output the second word of the header lines which you'd need to filter:

    awk '{if (NF > 1) print $2}' <file name> | egrep -v '[^-0-9.]'

You (almost) never need to pipe awk's output through (e)grep:

awk 'NF == 2 && $2 ~ /^[0-9]+\.[0-9]+$/ {print $2}' FILE
