Repeated observations of three binaries at specific orbital phases. Time constraints thoroughly specified in the README file. See also README file for priorities in case that more than one OB can be execute at a given time. Radial velocity standards included. Only 9 should be done, but 18 have been included to ensure that there is always some visible. Radial velocity standards must be done on nights when science OBs are done as well. This program has minimum seeing constraints, besides maximum seeing: observations should not be done with seeing under 0.7, as the line positions then become dependent on the position of the star across the slit. High precision required: wavelength calibration attached to each OB, flat field also to the science OBs. Note that some OBs have NOFFSET=2, NEXPO=1, offsets=(0,0). This is all right and done on purpose -two exposures per OB with no offset in between.
