AstroBridge transients dataset
This dataset contains 987 ZTF BTS supernovae with accepted alert photometry, a Legacy Survey host image, and separate transient and host-image captions. The frozen broad-class counts are SN II: 314, SN Ia: 563, SN Ibc: 110.
The 18 columns are grouped as follows. object_id, host_image_id, and class_label identify the object, frozen host image, and broad class. lc_mjd, lc_flux_njy, lc_flux_error_njy, and lc_band preserve every accepted alert-photometry point in MJD order. Signed nJy values remain signed. atcat_flux, atcat_flux_error, atcat_band_id, atcat_use, and atcat_length store the aligned ATCAT arrays, using zero point 27.5, band IDs 1 for g and 2 for r, and excluded-band sentinel 0 for i.
image_flux, image_bands, image_modality, and display_image store the Legacy Survey host-image tensor, the DES-G/DES-R/DES-Z band labels, the modality tag, and the matching preview image bytes. The four Parquet files are deterministic balanced shards of one object-ordered dataset.
transient_caption and host_image_caption are synthetic training targets rather than direct observational measurements. The transient captions in this release were generated from the complete accepted alert-photometry table, a rendered chart of the same measurements, and private literature context restricted to relevant photometric information. The frozen broad-class label constrained the final classification sentence. Generated captions may contain interpretive language beyond strictly photometric description.
