Table 1: Instruments, filter properties and year of data acquisition of the high-resolution images of the IRS 13 field.
Table 2: Photometric measurements in all the filters, in log ( $\mu$ Jy), of all the stars detected by MCS deconvolution (Sect. 2.3) of the $2.5\hbox {$^{\prime \prime }$ }\times 2.5\hbox {$^{\prime \prime }$ }$ IRS 13 field from the H and Kp Gemini AO images. Measurements in the NICMOS filters (F) were obtained by StarFinder, and in the L band by MCS analysis. The sources are listed by order of decreasing brightness in the Kp band, except IRS 13W, which is listed first. Values preceded by < in the 1.1 $\mu$ m and the L bands are minima of detection, i.e. flux upper limits.
Table 3: Offsets from SgrA $^{\star }$ ^a of the sources shown in Fig. 2.
Table 4: Projected separation of the main IRS 13E sources. From the astrometry the precision on the distance betwen two sources is $\pm$ 15 AU.
Table 5: H, K and L photometry of the IRS 13E cluster and of the nearby field stars from Table 2.
Table 6: Amplitude of proper motions of the main IRS 13E sources (from Ott et al. 2003).
Table 7: Fitting parameters of the SED of the IRS 13 sources. The spectral type of each source, as discussed in Sect. 4, is summarized in the last column.
