and provide a highly accurate wavelength fiducial. The full analysis procedure is explained in @butler, but in short, the velocities are measured by comparing each star+I2 spectrum to that of a template measurement of the same star. This template is observed without the I2 cell in place, such that one can deconvolve the instrument’s PSF from the template observation, usually accomplished by observing a rapidly rotating B-star with the I2 cell in place before and after the template observation and extrapolating the PSF from these observations to that of the template. The deconvolved template can then be used to forward model each observation by convolving it with a very high resolution and high S/N I2 spectrum and a modeled PSF. The final stability of MIKE is found to be between that of CORALIE and HARPS, around the 5 level of velocity precision.
