Generation 2 — Data

SBN Production — Gen 2 Data Samples

Data (Unblinded)

Unblinded data is available for use and doesn’t require access requests.


BNB + Light Data


The primary neutrino stream for SBND physics analysis.

Run 1 Analysis Development Sample (Fix + Rolling)

  • calibntuples: data_MCP2025C_Fall25-Run1_BNB_Dev_bnblight_v10_14_02_histreco2_sbnd

Run 1 Rolling Analysis Development Sample

Documentation: Check DocDB 44638 for the specific run list used in the Rolling Sample.
Usage: Rolling Dev sample is a good place to check the time-dependent signatures present in analyses.

Run 1 Fixed Analysis Development Sample

Documentation: Check DocDB 44638 for the specific run list used in the Fixed Development Sample.
Usage: The fixed sample is a good place to start an analysis because its data is taken over a short time period and shouldn't contain time-dependent signatures.
