The LAMOST Medium-Resolution Spectroscopic (MRS) survey works at R~7500 in optical (5000-5300A and 6300-6700A). To deliver a sample of spectroscopic binaries, a series of analysis should be done.
-
Step1: measure radial velocities of B & R spectra respectively
-
Step2: pick out SB2 systems
-
Step3: correct the zero-point shift between epochs (using a sample of single stars)
-
Step4: determine the mass ratio and orbital parameters
-
Step5: determine the fundamental parameters of EB-SB systems
