Engineering mnemonics for the four visits of GJ 3929 b prior to observation. The sa_zattest engineering mnemonics indicate the pointing of the telescope, with the y-axis arranged such that the telescope is on target when the curves converge to zero. The filters are ordered to accurately reflect the rotation of the filter wheel. The pre-flashing detector-settling slope experiment has the filter change to P750L before slewing to the target. The first visit is discrepant in that it spends very little time in this filter, which may impact the systematics present in the rest of the visit.
