The grating spectra of these two systems were obtained at the Sutherland Station of the South African Astronomical Observatory in 2013. Radial velocities of the components were determined by the Fourier disentangling technique. Keplerian radial velocity models of HO Tel and QY Tel give their mass ratio as 0.921 +/- 0.005 and 1.089 +/- 0.007, respectively.eninfo:eu-repo/semantics/closedAccessConference Object496258259N/AWOS:000369467900050
