## 2. Observations and data analysisIn our analysis we used all the publicly available data obtained from RXTE archive including 24 pointed observations. The 24 observations quasi evenly cover the 1998 outburst of the source with a total exposure of ks. The list of observations is presented in Table 1.
For data reduction we used the standard FTOOLS package version 5.0 For the spectral analysis we used PCA data collected in the 3-20 keV energy range. The response matrix was constructed for every observation using pcarmf v3.5. For the PCA background subtraction we applied a Very Large Events (VLE)-based model. The standard dead time correction procedure was applied to the PCA data. In order to account for the uncertainties of the response matrix, a 1 systematic error was added to the statistical error for each PCA energy channel. HEXTE data reduction was done with FTOOLS 5.0 standard tasks and according to RXTE GOF recommendations. We generated an averaged energy spectrum of XTE J2012+381 for each of the 24 observations. The spectral data were approximated with the simplest two-component model: the sum of the XSPEC "multicolor disk black body" (Mitsuda et al. 1984) and a simple power law model with inclusion of a broad gaussian emission line at 6.4 keV. The results of the spectral approximation of the PCA data with analytical models described above are presented in Table 2.
