VOSA SED model fits (corrected for extinction) for various data sets of flux measurements for NY Hya. The horizontal lines in the residual plots mark ±3σ deviation from the model. Panel A: WISE and 2MASS flux measurements $({\chi }_{\nu }^2=1.2)$. Panel B: WISE, 2MASS, and GALEX fluxes $({\chi }_{\nu }^2=6.0)$. Panel C: almost all available archive data with < 10σ deviations (${\chi }_{\nu }^2=15.3$; see Table 9 for details). Panel D: only retaining flux measurements around 7000 Å $({\chi }_{\nu }^2=17.6)$. The APASS Sloan i measurement deviates at a 8 − 9σ level (see text for details). Some error bars are smaller than the symbol size. In all cases, no infrared excess was detected eventually pointing towards a circumstellar disc and/or a cool companion. We also note that data for each model has been thinned to reduce data size.
