To achieve a meaningful outcome, an accurate selection of the target sample is needed. In this paper we analyse the targets, suitable for EChO observations, expected to result from a sample of present and forthcoming detection surveys. Present day discovered exoplanets are sufficient to provide a large and diverse sample. However we expect that results from ongoing and planned surveys, aimed at identifying new planets, will increase the sample of smaller planets allowing us to optimize the EChO sample selection. The analysis of the expected yields of a representative set of those surveys both from ground and space shows that they will be able to provide a large number of targets, covering an ample range of planetary and stellar parameters, fitting the EChO capabilities. <P />STAMPAenArticle10.1007/s10686-014-9412-32-s2.0-84952982501000367627900012https://link.springer.com/article/10.1007%2Fs10686-014-9412-32015ExA....40..577MFIS/05 - ASTRONOMIA E ASTROFISICAScienze Fisiche Settori ERC (ERC) di riferimento::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation
