Special Remarks:
All the OBs corresponding to one object have to be observed during the _same_ night
Abstract for MTS:
The program is going to measure the radial velocity (Vr) value of the faint binary companion. Program needs a long total exposure (2 to 4 hours) in order to obtain with FEROS a low signat-to-noise spectrum of the faint secondary component. For that reason all spectra for one object should be observed during the same night otherwise the short period Cepheid pulsation will blend the spectral lines and the Cepheid spectrum
will then be useless.
Also if Cepheids OBs have been scheduled, then _one_ velocity standard star must be observed during the same night.
