Look into the script "mrtg" (the mrtg program) and search for the string
"RRA" (around line 415). You will find

            my @args = ($rrd, '-b', $time-10, '-s', int($interval * 60),
                         "DS:ds0:$up_abs:$minhb:0:$absi",
                         "DS:ds1:$up_abs:$minhb:0:$abso",
                         "RRA:AVERAGE:0.5:1:600",
                         "RRA:AVERAGE:0.5:6:700",
                         "RRA:AVERAGE:0.5:24:775",
                         "RRA:AVERAGE:0.5:288:797",
                         "RRA:MAX:0.5:1:600",
                         "RRA:MAX:0.5:6:700",
                         "RRA:MAX:0.5:24:775",
                         "RRA:MAX:0.5:288:797");
            RRDs::create(@args);
