JWST mnemonics which track telescope orientation (sa_zattest) overlaid with the mnemonic tracking current MIRI filter position. Left y-axis shows difference in telescope pointing parameters from our observations. Filter wheel position is plotted as black dashed line and corresponds to right y-axis, including any intermediate filters rotated through. In all three eclipses, coarse slewing towards the target finishes ~ 15 minutes before the observation starts, leaving time for persistence effects from the last filter used.
