Let us assume that this string is in $_

($meanH1, $meanH2) = /^\s{9}(.*?)\s{10}(.*?)$/;

# Or you may be able to generalize it a bit more with:
($meanH1, $meanH2) = /^\s*(.*?)\s*(.*?)\s*$/;

# Or, if the second option is true, you could event use:
($meanH1, $meanH2) = split;

# Which is a short hand version for
($meanH1, $meanH2) = split /\s+/, $_;

All of the above are rather basic examples of regex and are well documented in perlre (perldoc or perldoc.com)
