Adding PMT Analysis

[pietro14]

Now, camera and PMT analysis can be performed together or separately.

You can use the flags "camera_mode" and "pmt_mode" to choose which analysis to perform.

If both flags are set to 1, the final output file will contain 3 trees:

1. Events: A tree containing reconstructed quantities for the camera.
2. PMT_Events: A tree containing reconstructed quantities for the PMTs.
3. PMT_Avg_Events: A tree containing the average PMT waveforms of 4 channels.

In the future, the following improvements will be needed:

• Integration of Bayesian fitting to associate each waveform with a single cluster.
• Merging the 3 trees into one single tree where each event contains information about a single cluster and the associated waveform (note that currently, an event is an image).

For more information about the PMT analysis, please contact David.

(The code has been tested and runs smoothly.)
