Analysis scripts
Pflib has a wide variety of data analysis and plotting Python scripts, located in the ana/ directory. These scripts serve to interpret the data gathered via pftool DAQ functions. This page contains the documentation for some of them.
- RMSD - root-mean-square deviation, equivalent to standard deviation. In the scripts often referred to as RMS;
The pedestal/averagesplot.py script allows the user to determine the mean pedestal values across link 0 (channels 0-35) and link 1 (channels 36-71). The code also calculates the RMSD across samples of each channel and across each link. For example, if the pedestals were taken with a 100 samples per channel, the channel-wise RMSD would be the stddev of the 100 samples. The link-wise RMSD would be the stddev of the mean pedestal values of each link.
Both the mean pedestal values and the channel-wise RMSD can be plotted for each link, as seen in examples below:
To engage with the different functions of the script, the user needs to provide an initial run setting. These can be found by running python3 averagesplot.py -h. The current settings are:
- -pd - Path to directory for saved figures;
- -lc - Mark the first pedestal file as pre-lowering and second as post-lowering;
- -rms - Calculate and save the RMS of the mean pedestals for each link - provide a file path.
An example that engages all the settings would be:
python3 averagesplot.py [pedestals.csv] [pedestals_lowered.csv] -pd [/plot_directory/] -lc -rms [link-wise-RMSD-results.csv].
