The program will commission and calibrate a specific mode of spectropolarimetry comma which will provide the most widely useful capability (mode) for the science community (R = 69 - 131) from 0.55 - 1.05 microns). In addition comma the new spectropolarimetry observations will confirm comma using on-orbit data comma the corrections for the perpendicular transmission d_commaleak comma d_comma which ground testing suggested rises sharply redward of 0.8 microns in the POLV filters comma and will help complete the recalibration of the polarimetry calibration coefficients using data from the recent calibration programs 13964 (PI McMaster) and 16008 (PI Desjardins).
