Angular diameter of the circumstellar emission measured in the three different filters.
|Calibrator||Filter||Dd,L [′′ ]||Dd,PSF [′′]|
|HD 169414||PAH-1||0.092 ± 0.004||0.103 ± 0.003|
|HD 187642||PAH-1||0.082 ± 0.005||0.101 ± 0.003|
|HD 169414||PAH-2||0.084 ± 0.003||0.096 ± 0.002|
|HD 187642||PAH-2||0.081 ± 0.002||0.087 ± 0.002|
|HD 187642||Si-6||≤0.024 ± 0.009||≤0.035 ± 0.011|
Notes. The uncertainty refers to the 1σd error as derived in Mariñas et al. (2011). The source is considered resolved if the deconvolved (in the sense of quadratic subtraction) diameter is larger than 3σd. The subscript L and P refer to the Lorentzian fit and to a direct measurement of the PSF profile, respectively.
