Data lineage and source analysis
Database link
SourceLink: SourceListID+SourceID (“SLID+SID”)

Data lineage & configuration of GALFIT run
• The usage of data lineage allows to run with SLID+SID as only input:
In red: info provided by data lineage

Grouping GalFit runs
• Analogy with SLID+SID: GFLID GFID

Next steps• Source analysis tools– Data lineage: splinter on SourceLink method
consistently (Ewout)– More tools for surveys?: collaborate with survey
teams• Create user-contributed corner in Astro-WISE– Re-ingest galphot/galfit subtracted images
Verdoes/Bos– Exports to aladin/topcat (Buddelmeijer/Belikov)– Relative astrometry Koppenhoefer– etc….
