Quality assessment test

To assess the performance of VOSA we have made a comparison with the Elodie library (v3.1).

For the comparison we have selected only those Elodie targets with a quality flag=4 ("excellent") in effective temperatures.

Then, for these targets, the observational SED has been built using photometry (Tycho, Stromgren and 2MASS) retrieved from VO services using VOSA.

An average value of Teff(VOSA)-Teff(Elodie)=-34 ± 150K is found for a sample of 116 objects.
