AstroBridge YSE external test dataset
This dataset contains 266 spectroscopically labeled YSE DR1 transients that do not overlap the final AstroBridge BTS training dataset by normalized TNS identity or a two-arcsecond transient-coordinate match. The broad-class counts are SN II: 71, SN Ia: 180, SN Ibc: 15.
Each row has at least five valid ZTF g and five valid ZTF r observations, ordered by time. The light-curve flux arrays are in nJy. The ATCAT arrays retain SNANA FLUXCAL at zero point 27.5, with band IDs 1 for g and 2 for r. Every ATCAT point is included.
The host image is a Legacy Survey DR10 South or DR9 North grz cutout. image_flux is a float32 [3,128,128] tensor in nanomaggies per pixel with bands [DES-G, DES-R, DES-Z]. display_image is rendered deterministically from the same tensor. Objects without an authenticated vetted host association and valid Legacy image are absent.
No captions, split assignment, flags, provenance fields, or other private construction metadata are present in the public Parquet rows. The shards form one deterministic dataset in object_id order.
