Orbital solution of Hα RVs from the mirror method.

Element	LOSP solution
P_orb	203.523 (adopted)
e	0.0 (adopted)
γ (kms⁻¹)	−10.8 ± 0.1
K_be (kms⁻¹)	4.1 ± 0.3
T₀ (HJD-2 450 000)	9197.5 ± 1.4
f(m) (M_⊙)	0.00146 ± 0.00031
rms (kms⁻¹)	1.02

Notes. γ is the apparent systemic velocity, K_Be stands for the RV amplitude of the Be star, and T₀ is the time of minimum RV of the Be star. f (m) is the mass function.
