        # 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")
