We use observations of a stable star with the WFC3 UVIS G280 grism in order to measure the followingdoublePoint 1) measure the UVIS shutter.s timing jitter comma i.e. the non-repeatability of a commanded exposure time due to the vagaries of the mechanical shutter mechanism (current best estimates are 0.004s rms or 0.006s rms) 2) validate if FLASH is important for very bright stellar spectrophotometric time series with G280 and 3) test effects of shutter BLADE (A or B) for the same.
