hitlets_nv
Description
Provided by plugin: nVETOHitlets
Data kind: hitlets_nv
Plugin which computes the nveto hitlets and their parameters.
Hitlets are an extension of regular hits. They include the left and right extension. The plugin does the following:
- Generate hitlets which includes these sub-steps:
Apply left and right hit extension and concatenate
overlapping hits. * Generate temp. hitelts and look for their waveforms in their corresponding records. * Split hitlets if they satisfy the set criteria.
Compute the properties of the hitlets.
- Note:
Hitlets are getting chopped if extended in not recorded regions.

online_monitor_nv
Description
Provided by plugin: OnlineMonitorNV
Data kind: online_monitor_nv
Plugin to write data of nVeto detector to the online-monitor. Data that is written by this plugin should be small (~MB/chunk) to not overload the runs-database.
This plugin takes ‘hitlets_nv’ and ‘events_nv’. Although they are not strictly related, they are aggregated into a single data_type in order to minimize the number of documents in the online monitor.
Produces ‘online_monitor_nv’ with info on the hitlets_nv and events_nv
Columns provided
| Field name | Data type | Comment |
|---|---|---|
| time | int64 | Start time of the chunk |
| endtime | int64 | End time of the chunk |
| hitlets_nv_per_channel | ('<i8', (120,)) | hitlets_nv per channel |
| events_nv_per_chunk | int64 | events_nv per chunk |
