Log of spectroscopic observations of HIP 71933 for our epochs. The first two columns list the epoch of the observation and telescope. Column 3 lists the instrument resolution. Columns 4, 5, and 6 list the date, start time, and end time for the exposures. Column 7 lists the number of usable exposures in the sequence. Column 7 lists the rotational cycles for each epoch from the first to last exposure. The zero phase was calculated to be the mid-point of the first epoch and is at JD 245 4932.2110 (see equation 1). The zero-points for all subsequent epochs are calculated as an integer number of rotations starting with the zero-point of the first epoch that is the closest to the mid-point of each epoch.
