Image Details
Caption: Figure 5.
Same proper-motion test as in Figure 2 for the companion candidates around LSPM J1002+1459 (left; the first and second epochs correspond to the date when the IRD-FIM image was taken and the NIRC2 observations on 2022 February 13, respectively) and LSPM J2204+1505 (right; the first and second epochs correspond to the NIRC2 observations on 2022 August 8 and 2022 November 8, respectively). In the left panel, the astrometric errors of the second epoch and the expected position in case of a background star turn out very tiny in the plot; therefore, we use star symbols for clarity.
