TSAP (SSAP theory use case)

The first attempt (as an ESAVO-SVO collaboration) to define such a protocol was TSAP (Theory Simple Access Protocol), designed to access theoretical spectra. Now TSAP is part of the SSAP protocol as a Use Case.

General information about TSAP

• SSAP protocol
• TSAP: how to use it (SVO web page)
• TSAP interface (an interface to check a TSAP service, check if it works as expected or retrieve data from it)

Model services using TSAP

• Web access to SVO theoretical spectra model services
• TSAP metadata interface to the models: (links point to the first TSAP dialog step: the format=metadata one. Subsequent queries can be made using this information)
  • Dalessio disk models
  • Kurucz ODFNEW/NOVER models
  • NextGen models
  • COND00 models
  • DUSTY00 models
  • Coelho models

Applications using TSAP

• VOSpec
  • An ESA-VO tool able to handle Spectra in the VO context as well as providing analysis capabilities and easy integration of spectra coming from different data providers, wavelengths, and different metadata
  • accesses theoretical spectra in the VO allowing to compare them with observed data.
• VOSed
  • An SVO tool that permits to characterize the protoplanetary disks around young stars taking advantage of the already existing VO standards and tools.
  • uses TSAP to access Dalessio models to fit observed data.
• VOSA
  • a web application developed using VO resources to fit observational data with theoretical models to infer physical properties for the observed objects.
  • uses TSAP to access several theoretical spectra collections and synthetic photometry corresponding to those spectra and find the best fit for observed photometry.
