PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 2 Introduction –Required component of the IVOA SED effort –Effort focused in adding what it was missing from current known specifications (Spectrum DM & Characterization) –DM authors covers main IVOA groups involved on photometry: P. Osuna, D. Baines (ESAVO) C. Rodrigo (SVO) M. Louys, M. Allen, S.Derriere (Strasbourg/CDS) E. Hatziminaoglou (ESO) J. McDowell (VAO) –Authors are technicians and scientists –Draft was reviewed by EuroVO Science Advisory Committee so we get good inputs and ideas from scientific point of view

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 3 FILTER PROFILE PROFILESERVICE(SVO) Give me list of registered Filters (possible constrained by wavelength range) Response, VOTable Give Details for a certain filter list Response, VOTable Including link to Transmission curve Show filters so user can select Use filter Details to create synthetic photometry points using real/model spectra as input FILTERPROFILESERVICEPROTOCOL Initial first use case: Synthetic Photometry

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 4 FILTER PROFILE PROFILESERVICE(SVO) PHOTOMETRYDATASERVICE(SVO) PHOTOMETRYDATASERVICE(CDS?) PHOTOMETRYDATASERVICE(others?) SSAP like query To be defined (Photometry details attached or by filter ID) or by filter ID) FILTERPROFILESERVICEPROTOCOL Initial second use case: Photometry in catalogs

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 5 FILTER PROFILE PROFILESERVICE(SVO) PHOTOMETRYDATASERVICE(CDS) Cone Search like query VOTable + Groups FILTERPROFILESERVICEPROTOCOL Final second use case: Photometry in catalogs

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 6 Vizier implementation –IVOA note was produced to describe how to include photometry characterization in groups in a catalog VOTable response –This can be used for Cone Search and TAP services –Relevant utypes of the Photometry DM WD are used so applications can handle the photometric information –More than 200 catalogs are being adapted in Vizier to include this information (acknowledge to F. Ochsenbein and S. Derriere) (ASU syntax for queries) –Some of them have been already included in VOSpec as a proof of concept UGC2826_2MASS_phot.xml UGC2826_NVSS_phot.xml –Cone Search services have been updated to latest PhotDM –These services could be registered using the photometry capability (Nice to have)

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 7 Vizier implementation (II) –Example for 2MASS – c.rs=5http://cdsarc.u-strasbg.fr/viz-bin/test/votable/-P?-source=2246&-c=3C273&- c.rs=5 –New added feature recently added: – –Catalog selection (-source= parameter) can be removed, All photometric information for all vizier catalogues, provided you give a center target. Example for 5 arcsec search around 3C273

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 8 Filter Profile Service Description –Provides a way to retrieve information about filters –More than 1700 filters. –Web interface –description –graphs –properties –zero points VO service –Retrieving information about a filter knowing its ID –Retrieving information about a filter and its calibration knowing PhotCalID –Searching for filters: SSAP-like service

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 10 Filter Profile Service (III)

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 11 Filter Profile Service (IV)

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 12 VOSpec implementation –Access to SSAP like services including photometric data –Access to Cone Search services including photometry capability –Access to Filter Profile Service to get Filter descriptions –Module to use transmission curve to generate synthetic photometry

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 13 Pending improvements in VOSpec –Integrate version with the recent services updates. No major problem is expected as neither FPS nor Cone Searches have reported problems during the update to latest DM version (Required) –Explore new vizier service features (A real nice to have) –Discover cone search (TAP?) services from the registry by using the photometry capability (Capability not defined and changes expected in registry) (Nice to have) –Develop specific registry navigation of cone search services (Nice to have) –Explore Filter Profile Service interface with a dedicated panel (This can be done already although it would be better to have a Filter Profile Service protocol defined) –As soon as we have a stable Spectrum 1.2, adapt SSAP/Spectrum parser to consume photometric information (Future feature)

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 14 Photometry DM 1.0

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 15 Photometry DM 1.0 (II) –New version 1.0 (13/10/2011) under author list discussion –This version includes two types of changes: –“Introduction” and “Astronomical Photometry” sections updated –Some minor changes in the model itself (only some utypes and description updates in line with other IVOA data models) –Pending: Find possible optical-biased terms in the text. Preliminary analysis shows that this does not produce implementation problems –Integrate the different updated implementations –Distribution to the working group and external reviewers (extra effort is required) –If no major problems are found in the model, start RFC process

PhotDM implementation feedback | Jesus Salgado | ESAC | 18 October 2011 | IVOA Pune 2011 | Pag. 16 Other specifications pending issues – Describe the photometry capability so cone search or TAP services can be properly registered and discovered (not necessary for PhotDM although useful) – Describe Filter Profile Service as a separate note (work to be done in coordination with DAL group) – Follow-up of Spectrum 1.2 evolution (that will include PhotDM utypes)
