Assigning as draft as I am still extracting neccesary filter info

I have confirmed that after the running the filter on a generated sample of beam + corsika + rockbox, that there are events in my output file. Below are the relevant metrics. I have also attached a file that shows the end of the art log file wth the summaries. -> filter_end_log.txt

Filter Performance Metrics (Based on 11,794 generated events):

• Filter Efficiency: 14 / 11,794 events (~0.12% retention for the hyperon stream)
• Average CPU Time (hyperon filter module): ~0.026 seconds / event
• Output File Size: 525 MB total (~37.5 MB / saved event)

Looks good to me. Pending other reviewers.
@tjones79 could you confirm you see your desired events in your test?
@tbwester could you please review?

Hi @linyan-w

I can confirm that the 14 events filtered were indeed events that contain hyperons, as desired :)
