Straxen nT datastructure for high energy channels
This page is an autogenerated reference for all the plugins in straxen’s xenonnt_online context.
The figures presented are dependency diagrams, meaning that an arrow stemming from a node points to a node that the stem depends on (i.e. “A depends on B” is equivalent to “A —> B”).
Colors indicate data kinds. To load tables with different data kinds, you currently need more than one get_df (or get_array) commands.

peaklets_he
Description
Provided by plugin: PeakletsHighEnergy
Data kind: peaklets_he
High energy channels: attenuated signals of the top PMT-array
- Split records into:
peaklets
lone_hits
Peaklets are very aggressively split peaks such that we are able to find S1-S2s even if they are close to each other. (S2) Peaks that are split into too many peaklets will be merged later on.
- To get Peaklets from records apply/do:
Hit finding
Peak finding
Peak splitting using the natural breaks algorithm
Compute the digital sum waveform
Lone hits are all hits which are outside of any peak. The area of lone_hits includes the left and right hit extension, except the extension overlaps with any peaks or other hits.
