# BGRS
**Quick facts:** full: 1089977 rows • filtered_train/test combined: 1083363 rows • Vector dim: 7781
**Description:** This dataset contains scalar metadata (from FITS HDU 1) together with dense per-row vectors extracted from HDF5.
## Splits
- `full` — all rows
- `train` — 80% of filtered selection (criterion: GALAXY delta_z < 0.0033 or QSO delta_z < 0.01)
- `test` — 20% of filtered selection
## Usage
```python
from datasets import load_dataset
ds_full = load_dataset("AndyMorgan-NOIRLab/BGRS", split="full")
ds_train = load_dataset("AndyMorgan-NOIRLab/BGRS", split="train")
ds_test = load_dataset("AndyMorgan-NOIRLab/BGRS", split="test")
