Magnitude of G2/DSO in different wavelengths. The pink data points are adapted from Peißker et al. (2021a), whereas the black and brown data points are incorporated from Pfuhl et al. (2015) and Witzel et al. (2014), respectively. The L-band data points from 2008 (NACO) and 2019 (NIRCAM2) are included. The Brγ line luminosity after 2014 is based on the analysis presented in Peißker et al. (2021a). The dashed line for every data set represents a first-degree polynomial fit and underlines the almost constant magnitude and luminosity in strong contradiction to the expected variation discussed in Gillessen et al. (2012), Ballone et al. (2013), and Pfuhl et al. (2015). Here all the uncertainties are estimated from the standard deviation of the related data set.
