Positional offsets of the 18 epochs relative to the millimeter continuum peak C1 in the NEOWISE W2 band, with the corresponding error bars representing the position uncertainties. The (0, 0) point is R.A. = 18^h35^m08.ˢ139, decl. = ﹩-07^\circ 35^{\prime} 04\buildrel{\prime\prime}\over{.} 17﹩ (J2000), which is the position of the millimeter continuum peak C1 measured with ALMA band 6 by Hirota et al. (2022). The color bars represent MJD (left panel) and the W2 magnitude of G24 (right panel).
