’SED Service’: Science Application based on Virtual Observatory Technology

We describe the development of a Spectral Energy Distribution (SED) matching technique using the current technology available through the Virtual Observatory. We outline the making of a detailed workflow technique that can take observational data of objects from various astronomical data archives and matches them to models generated through various model codes available. The result of running this workflow will produce plots of the best fit models to the data along with tabular data representing the best fit model and the closest matches, a standard error analysis on various physical parameters such as stellar mass and finally a set of image cutouts of the object. The technique will utilise various VO tools for data discovery, data access and data processing within AstroGrid, the UK’s Virtual Observatory initiative.
