$T_{\rm Fratio}~[{\rm K}]$	( $610\pm 180$ )		( $460 \pm 100$ )
$T_{\rm sphere,~8}~[{\rm K}]$	( $830 \pm120$ )		(480... $630\pm70$ )
$T_{\rm sphere,~13}~[{\rm K}]$	( $1020\pm210$ )		(400... $580\pm 90$ )

^a The individual component fluxes and sizes have uncertainties of about 15% and 10%, respectively, within the model. The additional uncertainty range of the flux contribution of the larger component due to the lack of data at short spatial frequencies (Sect. 3.4.1) is indicated with dots.
