Supernova & transient photometry, 11 catalogs — L1 (release v1)

This L1 repository contains 627 events matched across the release from YSE DR1, SNLS, Swift, Foundation, PS1, DES-Y3, CSP, CfA3, CfA4, CfA stripped-envelope, and CfA SN II. Each catalog has its own Parquet file, with a survey column added. The measurements retain their native values.

Schema

Per event: lightcurve struct with time, band, and either flux/flux_err (YSE, SNLS, Swift, Foundation, PS1, DES) or mag/mag_err (CSP, all CfA) — each catalog keeps its native representation, time convention, and filter names. Event metadata (redshift, type, host) as provided by each source.

Caveats

—L1 keeps each catalog's flux or magnitude representation. kshitijd/mmu-l2-sne provides an L2 sequence format with a representation column and one reversible scale per object.
—Time scales and calibration systems remain native to each survey. Use documented conversions when combining surveys.
—Version 1 includes retrospective splits. Temporal and forecasting tasks need an explicit prefix manifest.
