Spectral energy distributions presenting NuSTAR and Swift-XRT observations for six epochs (3 in 2013 and 2021). Swift-XRT observations are corrected for the influence of the hydrogen Galactic column density with N_H provided by Willingale et al. (2013). The last two digits of the label denote the ObsIDs of the NuSTAR observations. The Swift-XRT and NuSTAR observations are distinguished by filled and hollow markers, respectively. The full ObsIDs are listed in Table 1. In the case of 2013 NuSTAR data, spectral points are adopted from Wierzcholska & Wagner (2020).
