Comparison between input and output plasma parameters. Top left: histogram of (gray) input, (red) derived by moments, and (blue) derived by fit plasma density. Top middle: histogram of the input and derived plasma speed and (top right) the input and derived thermal speed in the same format. Bottom left: Histogram of (red) derived by moments and (blue) derived by fitting density divided by the input density. Bottom middle: Histogram of the derived over input speed. Bottom right: histogram of the derived over input thermal speed in the same format.
