Sources Saved - May 2026
Data
ZTF/LSST ID - Sources are cross-matched between surveys by cone-searching at the position of the latest alert; each source carries an ID for every survey in which it has been detected.
Peak, first & last - All photometric statistics are derived from the combined ZTF + LSST light curve. The listed filter and survey identify the specific detection from which each value was measured.
Data source - Photometry, spectroscopic classifications, host redshifts, and follow-up status are retrieved from Fritz, the LIONS group alert marshal.
Tables
Sources are split into Unclassified (top), Classified (middle), and Poor Observability (bottom) tables, each ordered by last magnitude (brightest first).
Row colours
Classified source
Low-confidence classification (<0.5)
Poor observability (<3 hr above airmass 2) — shown in separate table below, excluded from sample
Magnitude trend (mLast)
↑ Getting brighter — magnitude decreased vs. previous detection (>1 d ago, same filter)
↓ Getting fainter — magnitude increased vs. previous detection (>1 d ago, same filter)
↑ First detection in this filter band
↓ Latest point is a non-detection
