The primary neutrino stream for SBND physics analysis.

Documentation: All Gen 1 data samples are described in DocDB 44638. Check there for the specific run lists used in each Development Sample.

Run 1 Fixed Analysis 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.

Run 1 Rolling Analysis Development Sample

Usage: The rolling sample is a good place to check the time-dependent signatures present in analyses.

Run 2 Fixed Analysis Development Sample

Note: This sample does not contain POT accounting information.

Run 2 Rolling Analysis Development Sample

Coming soon!

Validation & earlier productions: The samples below are validation campaigns and earlier reconstruction passes of the development samples above.

Fall25 Validation — Full Run 1 Rolling Dev (BNB + Light)

Note: Full Run 1 rolling development validation sample (~75k events). This sample does not contain POT accounting information.

Fall25 Validation — Full Run 1 Rolling Dev (BNB + Light, DNN)

Note: DNN reconstruction variant of the Full Run 1 rolling validation sample (~75k events).

Spring25 Fixed Dev Sample (5e18 POT) — Earlier Productions

Note: Earlier reconstruction passes (~90k events) of the Run 1 fixed development sample.

Spring25 Rolling Dev Sample — Earlier Productions

Note: Earlier reconstruction passes (~30k events) of the Run 1 rolling development sample.

Spring25 Validation Dev Sample

Note: Early Spring 2025 validation production (MCP2025Av3, ~90k events) of the development sample.

BNB Summer 2024 Data (Keep-Up)

Note: Legacy Summer 2024 keep-up BNB data (zero-bias + sunset triggers).

Integration Note: This sample is intended to be combined with BNB+Light data for accurate cosmic background estimation. When combining with BNB+Light data, don't forget to scale the off-beam by an additional (1 - 0.0754).

Run 1 Sample

Run 2 (1.5%) Sample

Validation & earlier productions: Kept for reference; for analysis, prefer the current v10_06_00_09 reprocess samples above.

Fall25 Validation — Full Run 1 Rolling Dev (OffBeam + Light, DNN)

Note: DNN reconstruction of the Full Run 1 off-beam rolling validation sample (~40k events).

Run 1 Sample — Earlier Productions

Note: Earlier reconstruction passes of the Run 1 in-time cosmic (off-beam) sample. The current v10_06_00_09 production is listed under “Run 1 Sample” above.

Zero-bias (minimum-bias) trigger samples from Run 18115 (Feb 2025 workshop).

Run 18115 BNB Zero Bias

Note: ~610k events.

Run 18115 OffBeam Zero Bias

Note: ~240k events.

Crossing-muon calibration samples.

Crossing Muon (After-Light Trigger) — Full Run 1

Note: Full Run 1 crossing-muon sample (~30k events) on the after-light trigger.

Feb25 Workshop Calibration / Crossing Muons

Note: Early calibration productions (reco1 only available).

Run 1 1e20 Sample

Run 1 Full 1e20 POT Sample

Note: Full Run 1 1e20 POT BNB dataset (~1.7M events). The v10_06_00_09 rows are the Spring 2025 reprocess.
