Two-sigma upper limits on the radius of an exomoon around LP 890-9 c derived under various choices of how many epochs to include among the full set of 12 that were available. Set 1 (circles) iteratively drops epochs in reverse observation number. Set 2 (squares) only includes a single transit, of which there are 12 possible realizations. Set 3 (diamonds) included 12 representative pairings of two epochs.
