The MINiature Exoplanet Radial Velocity Array (MINERVA) is a dedicatedobservatory of four 0.7m robotic telescopes fiber-fed to a KiwiSpecspectrograph. The MINERVA mission is to discover super-Earths in the habitablezones of nearby stars. This can be accomplished with MINERVA's uniquecombination of high precision and high cadence over long time periods. In thiswork, we detail changes to the MINERVA facility that have occurred since ourprevious paper. We then describe MINERVA's robotic control software, theprocess by which we perform 1D spectral extraction, and our forward modelingDoppler pipeline. In the process of improving our forward modeling procedure,we found that our spectrograph's intrinsic instrumental profile is stable forat least nine months. Because of that, we characterized our instrumentalprofile with a time-independent, cubic spline function based on the profile inthe cross dispersion direction, with which we achieved a radial velocityprecision similar to using a conventional "sum-of-Gaussians" instrumentalprofile: 1.8 m s$^-1$ over 1.5 months on the RV standard star HD 122064.Therefore, we conclude that the instrumental profile need not be perfectlyaccurate as long as it is stable. In addition, we observed 51 Peg and ourresults are consistent with the literature, confirming our spectrograph andDoppler pipeline are producing accurate and precise radial velocities. 041b061a72
