Access to Stellar Population Models in the Virtual Observatory

TL;DR

This paper discusses integrating stellar population models into the Virtual Observatory, enabling easier access to synthetic galaxy spectra through HTTP and web services for scientific research.

Contribution

It introduces two methods for accessing PEGASE.HR models within the Virtual Observatory framework, enhancing data accessibility for researchers.

Findings

Implementation of HTTP-access via SSAP for limited parameters

Development of a full-featured web service using CEA

Facilitation of synthetic spectra retrieval for astronomers

Abstract

A great effort is being made by the international Virtual Observatory community to build tools ready to be used by scientists. Presently, providing access to theoretical spectra in general, and synthetic spectra of galaxies in particular, is a matter of current interest in the Virtual Observatory. Several ways of accessing such spectra are available. We present two of them for accessing PEGASE.HR evolutionary synthesis models: HTTP-access to a limited number of parameters using Simple Spectral Access Protocol (SSAP), and full-featured WEB-service based access using Common Execution Architecture (CEA).
