Caption: Figure 8.

Left: 5σ contrast limit of the postprocessed ﹩L^{\prime} ﹩-band data in our observations. We utilized RDI for the LSPM J0044+0907 data set and ADI for the other data sets. We also present the detected companions from the NIRC2 ﹩L^{\prime} ﹩-band observations (LSPM J0825+6902 B, LSPM J1645+0444 B, and LSPM J2204+1505 B), indicated by red circles. Right: converted mass limit from the contrast limit overlaid with the detected companions as shown in the left panel and the COND03 evolutionary model assuming 1 and 10 Gyr.
