Averaged NuSTAR FPMA data from GRS 1915+105 from the three epochs together with absorbed (top row) and intrinsic (bottom row) model B components. The total model (solid red line) consists of the sum of 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). Middle panels: residuals of the models to the data.
