Generic architecture for analyses on calibrated images

Generic architecture for analyses on calibrated
images

• Gijs Verdoes Kleijn
• OmegaCEN
• Kapteyn Astronomical Institute

2
Facilitating analysis beyond the calibrated image
stage

• Analysis software
• Image differencing VODIA/OmegaTranS
• Photometric redshifts PhotZ
• Galaxy surface photometry galfit(/galphot)
• Astro-WISE users likely use/develop more in
  future
• Goal
• Easy running
• Easy exploring input/output
• Easy access final results
• Method make new classes which run routine,
  contain input/output, plus connections to its
  dependencies.
• Status design ready presented now for final
  input

3
Bi-furcation in kind of analysis

• Immediate modelling of image data
• galfit, PhotZ, (galphot)
• Take input from SourceLists

Case A
SourceLists
Case B

• Further manipulation of images first
• OmegaTranS/Vodia
• Take input from RegriddedFrame

RegriddedFrames (,ReducedScienceFrame, CoaddedRegr
iddedFrame)
4
Case A starting from SourceList

• Modelling inputoutput stored in objects which
  also contain unique model ID, SourceListID
  (SLID)SourceID (SID)

General parameters GalPhotModel (config
parameters,creation_date,. SLID,SID,GPID)
Why two objects? practical reasonmake post-run
searching fast
GalPhot run on one galaxy
Parameters one ellipse GalPhotEllipse
(r,dr,flux,dflux, SLID,SID,GPID)

PhotZ example

• A sourcelist for each filter

PhotZ run on one galaxy
redshift parameters PhotZData (z,dz,ltzgt, SLID1,S
ID1,PhotZID)
redshift parameters PhotZData (z,dz,ltzgt, SLID2,S
ID2,PhotZID)
redshift parameters PhotZData (z,dz,ltzgt, SLID3,S
ID3,PhotZID)
redshift parameters PhotZData (z,dz,ltzgt, SLID4,S
ID4,PhotZID)

Why copy for each Sourcelist? practical

Case B starting from frames

• Vodia/OmegaTranS adding points to existing
  lightcurve

VodiaLightCurvePoint Parameters single difference

Vodia runs on one star

Summary

• Two kinds of ways to connect analysis on reduced
  data sources to image data
• Case A Via SourceLists
• Case B Via Regridded(/Reduced/Coadd)

• Further add-ons
• PlannedFavorite model flag
• Possible authorname in objects?
