1. The ASDC SED Builder Milvia Capalbi (INAF-ASDC) in collaboration with Paolo Giommi (ASI-ASDC), Giulia Stratta (INAF-ASDC), Roberto Primavera (ElsagDatamat) with some inputs from other scientists @ASDC

3. SED Builder v1.3 WEB based application available at : http://tools.asdc.asi.it/SED/ MySQL database system Java code Query to ASDC catalogs and external catalogs/services Possibility to upload user data Manage private catalogs – login authentication, users can share own data with a predefined group In the following, I will show the main functionalities of the tool and the steps to make it VO compliant.

4. Building a SED Input name or RA/Dec and search radius in the query form Choose the catalogs in a set covering the energy spectrum from radio to gamma ray Click on ‘ Load Data ’ button

5. Choose the catalogs Radio catalogs KUEHR PKSCAT90 DIXON GB6 SUMSS NVSS FIRST VLSS CRATES PMN WENSS NORTH20CM (flux 20 cm) NORTH20CM (flux 6 cm) NORTH20CM (flux 80 cm) WMAP5 (Freq. 23e9) WMAP5 (Freq. 33e9) WMAP5 (Freq. 41e9) WMAP5 (Freq. 61e9) WMAP5 (Freq. 94e9) Infrared catalogs AKARIPSC AKARIBSB X-Ray catalogs IPCSLEW IPC RASS WGACAT2 WFCCAT XRTDEEP TWOXMMICAT Gamma catalogs EGRET3 BAT39MCAT (15-30keV) BAT39MCAT (14-50keV) Fermi1FGL (200 Mev) Fermi1FGL (600 Mev) Fermi1FGL (2Gev) Fermi1FGL (6Gev) Fermi1FGL (60Gev) IBISSG4CAT (20-40 keV) IBISSG4CAT (40-100 eV) AGILE Grid External services access NED 2Mass SDSS7 USNOB1 USNO A2.0

6. Plot data and look at data tables

7. Overlay instrument sensitivity Sensitivity of instruments collecting data from space and from ground (some Cherenkov telescopes) can be added to the plot.

8. Fitting data Data can be fit with a polynomial function (more functions to be added soon)

9. Draw a Model An SSC model, analytical or numerical, can be added to the plot (computed with model parameters input by the user). Different models can be added and combined.

10. Luminosity scale Y scale can be changed from Flux to Luminosity and frequencies from observed to rest frame (Redshift to be provided).

11. Adding Templates Templates (QSO or a giant elliptical galaxy spectrum) can be added to the plot

12. Plot options The marker type, color and size for each catalog can be chosen by the user Change axis interval Export data in an ascii file Save image in PNG format Background color can be changed and others……….

13. Time filtering of data (still in devel area)

14. Making ASDC-SED VO compliant Planned steps: Save data as VOTable Change query to DB: access of data via VO protocols instead of direct SQL access in our database Query the registry – Identify data useful to build a SED – via e.g. TAP – Get the necessary info to apply specific operations on data, when needed (*) Communicate with other VO tools using the SAMP protocol In addition to the WebApp: develop a stand-alone tool (study phase) First steps will be implemented by the end of the spring

15. Making ASDC-SED VO compliant (*) Currently some of the catalogs we use (mainly X-ray catalogs included in our database) don’t contain flux information but count rates we calculate the flux density using information on instrument response and assuming a spectral model (and we correct for the galactic absorption) In the VO environment Querying the VO registry, we should get the necessary information to calculate the flux density with instrument-specific functions (we should support more missions/instruments) Further improvement Allow the user to specify an energy index (e.g. to model the spectrum used to determine the flux)

16. Summary Current status current functionality of SED Builder shown the tool uses some catalogs containing instrument measurements NOT in physical units the tool is used by some instrument teams (e.g. AGILE, Fermi, Swift- XRT) since we manage some password-protected catalogs Future project to make the tool VO compliant we would like to find the best strategy to proceed and interoperate with other VO tools THANK YOU
