Astro-WISE galphot models in ds9


Astro-WISE galfit models in ds9

Data lineage and source analysis
Data lineage and source analysis

Database link

SourceLink: SourceListID+SourceID (“SLID+SID”)

Data lineage configuration of galfit run
Data lineage & configuration of GALFIT run

In red: info provided by data lineage

  • The usage of data lineage allows to run with SLID+SID as only input:

Grouping galfit runs
Grouping GalFit runs

  • Analogy with SLID+SID: GFLID GFID

self.flaming_sids=([int(data[aid][0][1]) for aid in data.keys() if (data[aid][3][i_b]-data[aid][3][i_r])>0.8 and (data[aid][3][i_b]-data[aid][3][i_r])<1.3 and data[aid][3][i_r]>17.6 and data[aid][3][i_r]<19.3 and data[aid][3][i_zphot]>0.28 and data[aid][3][i_zphot]<0.4])

Next steps
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….
