Averaged NuSTAR FPMA data from V404 Cyg in the preflare (epochs 1–2) and outburst (epochs 3–5) stages as shown in Fig. 5, together with absorbed (top row) and intrinsic (bottom row) model B components. The total model (solid red line) consists of a sum of a blackbody component (dashed green line), a cutoff power-law component absorbed in and scattered off from the material in the line of sight (dotted blue line), scattered into the line of sight by the surrounding medium (dot-dashed light blue line), and unabsorbed or direct component (long-dashed yellow line). The middle panels show the residuals of the models to the data.
