[KIDS] QC catalogs for KiDS-INT-DR2, single-band sourcelists

Thu Nov 15 15:33:15 CET 2012

Dear CATALOG-QC-TEAM,

The QC for KiDS catalogs falls in 2 parts: single-band and 4-band QC.

* SINGLE-BAND SOURCELISTS

We have the following QC checks in place in KiDS-CAT (thanks!), is my 
understanding:

  *
       FWHM vs SNR. DONE in KiDS-CAT. NN+HB can send algorithm/code to
    HB so Hugo can check implementation in AWE.
  *
       star/galaxy separation. DONE in KiDS-CAT. NN+HB can send
    algorithm/code to HB so Hugo can check implementation in AWE.
  *
       limiting magnitude. FLB can send a matlab (actually octave
    script) performing the analysis of the S/N vs. 2''mag diagram to HB
    Hugo Buddelmeijer who adds algorithm to qcSourceLists_INTDR2.py
    <http://www.astro-wise.org/viewvc/awe/astro/experimental/kids/qcSourceLists_INTDR2.py?view=markup&sortby=date>
    <http://www.astro-wise.org/viewvc/awe/astro/experimental/kids/qcCatalogs_INTDR2.py?view=markup&sortby=date>

  The NN+HB / FLB+HB indicate that I think it will be useful to 
implement those in Astro-WISE acting upon the ingested KiDS-CAT 
sourcelists. Nicola and Francesco can send the relevant info/code to 
Hugo Buddelmeijer who coordinates the implementation in Astro-WISE.

The following QC checks are planned for implementation:

  *
    HB/DONE?: The qualityWISE link for KiDS-CAT sourcelists in
    Astro-WISE (example link in DBVIEWER
    <http://dbview.test.astro-wise.org/DbView?project=KIDS&set_cookie=&QSort=creation_date&QDesc=descending&2ndQSort=creation_date&2ndQDesc=descending&numrows=100&fcontext_project_only=on&show_expanded=no&Exportselect=NoDownload&class_str=SourceList&mode=table_res&depth=1&python_dict=%2528dp0%250AS%2527query%2527%250Ap1%250A%2528dp2%250AsS%2527expanded%2527%250Ap3%250A%2528dp4%250AS%2527SourceList%2527%250Ap5%250A%2528lp6%250AS%2527open%2527%250Ap7%250AaS%2527root%2527%250Ap8%250Aag5%250AasS%2527SourceList.chip%2527%250Ap9%250A%2528lp10%250AS%2527prefilled%2527%250Ap11%250AaS%2527link_property%2527%250Ap12%250AaS%2527Chip%2527%250Ap13%250AasS%2527SourceList.filter%2527%250Ap14%250A%2528lp15%250Ag11%250AaS%2527link_property%2527%250Ap16%250AaS%2527Filter%2527%250Ap17%250AasS%2527SourceList.instrument%2527%250Ap18%250A%2528lp19%250Ag11%250AaS%2527link_property%2527%250Ap20%250AaS%2527Instrument%2527%250Ap21%250AassS%2527derived%2527%250Ap22%250A%2528dp23%250As.&expanded_leaf=&expanded_leaf_type=&expanded_leaf_class=&derived_leaf=&node_state=&SourceList.expanded=open&SourceList.chip.expanded=prefilled&SourceList.filter.expanded=prefilled&SourceList.instrument.expanded=prefilled&SourceList.SLID.op=%3D&SourceList.SLID=5967351&SourceList.detection_frame.base=BaseFrame&SourceList.frame.base=CoaddedRegriddedFrame&SourceList.instrument.name=OMEGACAM&SourceList.instrument.name.op=%3D>)
    directs to the QualityWISE pages of their coadds. These show catalog
    based information: see example
    <http://quality.test.astro-wise.org/QualityWISE?object_str=SourceList&object_id=ce10420f2fbdeb45e0407d81e60e7648&project=KIDS>.
    These plots are NOT based on the KiDS-INT-DR2 catalogs. They use a
    different sextractor run. Should we do something about this?
  *
    FLB: completeness. FLB: you probably have best insight now how to do
    this.
  *
    GVK: spatial distribution of sources and flag values. GVK's
    proposal: a KiDS images with source/flag information overlayed as step1?

Summing these up: the CATALOG-QC-TEAM should verify we are not missing 
crucial basic ones:

  *
    CATALOG-QC-TEAM: CFHTLS at Terapix had its final release (T0007).
    One product is synoptic table of CFHTLS
    <http://terapix.iap.fr/cplt/T0007/table_syn_T0007.html>, giving
    access to QC plots/numbers. Which ones do you think are important at
    this stage for KiDS QC?

What does CATALOG-QC-TEAM deliver for KiDS-INT-DR2 single-band 
sourcelists?:
My proposal:
1.the QualityWISE page: those we have in hand, they come for free with 
Astro-WISE coadd production. Input on improving the plots presented 
there is welcome.
2. A set of additional plots and/or numbers per catalog that complements 
the QualityWISE page with KiDS-INT-DR2 specific stuff. This can be 
either presented as one page per coadd or gallery of a certain plot for 
the 52 single-band sourcelists. Danny is looking into how we can 
implement such a presentation. I see this set as an experiment from 
which we can choose how to develop QualityWISE for single-band 
sourcelists further after KiDS team meeting in December.

Discussion has opened: all input welcomed (keep emailing 
kids at astro-wise.org!)

Above information and more is contained at our wiki spot for 
CATALOG-QC-KIDS-INT-DR2 for single-bands:
http://wiki.astro-wise.org/projects:kids:data_deliveries:internaldelivery2.0_scratch#qc_based_on_single-band_catalogs

Regarding 4-BAND CATALOGS: I propose to leave that effort as a separate 
task. Details will follow in another email.

Best wishes, Gijs
