Introduction

In this section we provide a detailed example on how to use this application.

We will consider a case where the user has 2MASS, CFHT and IRAC photometry for ten objects and will show the complete VOSA workflow, step by step.

This example is just a subset of the physical case studied in Bayo, A., Rodrigo, C., Barrado y Navascués, D., Solano, E., Gutiérrez, R., Morales-Calderón, M., Allard, F. 2008, A&A 492..277B
