The ASDC SED Builder Tool description and Tutorial

Understand

The ASDC SED Builder (http://tools.asdc.asi.it/SED/) is a web based program developed at the ASI Science Data Center to produce and display the Spectral Energy Distribution (SED) of astrophysical sources.

• The tool combines data from several missions and experiments, both ground and space-based, together with catalogs and archival data.
• In the current version (v1.3) the obtained SEDs can be compared with theoretical expectations and with the sensitivity curve of several widely known instruments.
• The displayed data can also be fitted to simple analytical functions.
