Comparison of K_s- and L′-band proper motions in right ascension and declination for the GC IRS13E and the IRS13N cluster (indicated by circles in dashed lines). The direction of the motion, i.e., S to N, or E to W, is labeled. The source labels correspond to those in Table 3. The K_s-band motions derived here are labeled with open dots. For IRS13 and for IRS13N the filled dots indicate the proper motions published by Fritz et al. (2010) and Muzic et al. (2008). The open circles depict the K_s-band proper motions described here.
