Weighted spectropolarimetric analysis of GX 349+2 and GX 340+0 using a spectral model with a soft disc component, a hard Comptonised one, and a Gaussian Fe line.

Spectral component		GX 349+2	GX 340+0 NB ^(a)	GX 340+0 HB ^(b)
`diskbb`	PD (%)	1.0 ± 0.7	< 1.2	3.1 ± 1.7
	PA (°)	$6_{- 23}^{+ 24}$ $6 _{-23}^{+24}$	–	−1 ± 16

`Comptonisation`	PD (%)	3.7 ± 3.0	4.3 ± 1.8	5.2 ± 1.0
	PA (°)	68 ± 26	44 ± 13	44 ± 5

Notes. A polarisation with zero amplitude is associated with the Gaussian Fe line component in all the spectra. The errors are reported at 90% CL.
