Caption: Figure 1.

Point-spread-function (PSF) of echelle spectrometers with an Iodine cell, in the middle of the Iodine absorption region. In each case the PSF is from an observation of a star, taken through the Iodine absorption cell. The red line is the PSF from the UVES, taken through the fiber slicer, which yields an effective slit of 0.″3. Blue and green lines are from the PFS spectrometer with slit widths of 0.″3 and 0.″5, respectively. HIRES is shown in black. The slit width and resolution of each spectrometer are listed in the figure.
