Log - Take the log of data
<in.H Log [range=3 centered=2] > out.H
defines the smallest allowed value.
Defining max to be the maximum of the logs (best
signal), output values (bad signal) below (max-range)
are set to (max-range). Often you might choose range
to be a small integer, for example, range=3 means
each input handled as max(input, biggest/1000).
defines method of shifting mean of log.
0-The max is subtracted so all logs are negative.
label2="log base 10" is putched
1- The average of max and (max-range) is subtracted.
(effectively scaling the original data)
pclip=100 is putched.
2-The average value of all the logs is subtracted.
range=2*(max-avg) is putched.
