PRVS is a precision radial-velocity spectrometer that aims to attain 1m/s precision in the near-IR. It is scheduled to be added to the Gemini suite of instruments by 2011. Therefore, we are currently preparing a number of precursor programs to fully exploit the science that PRVS will provide. One of the main aims of PRVS will be discovering planets around cool substellar objects. Therefore, we have selected a candidate list of cool stars that will provide ideal targets for PRVS. We firstly have selected a number of bright M-dwarfs and measured their rotation velocity (v sin i) using HRS on the HET. A deconvolution technique was used to generate high S/N line profiles using a cool atmosphere line list from the VALD database. The slowest rotators will be the high priority targets for our PRVS planet search project since they will provide the lowest noise thresholds and best sensitivity. I will discuss both the methodology and initial results from this work and then explain where the project will lead in the future.
