Examples of Output Plots

Shown below are a number of example of the output plots which can be displayed through the EUVSim application.

No Smoothing, No Decimation, Polar

The four figures below show output from an inversion run in which the Measured Image was neither smoothed or decimated. A polar coordinate system was used for the solution matrix and the Max Z used in the formation of the zero solution was 6.0 with a step size of .01.

Clockwise from the upper left:
Measured Image, Simulated Image, Error and L-Shell plots. The large deviations in the Error Plot genereally occur where the total countrate is low and often at pixels where either the Synthetic Image shows intensity and Measured Image doesn't or vice versa.

No Smoothing, Input Decimated

The set of three figures below show output for an identical run as above except that the measured input has been decimated by a factor of 2. Note the change in the zero solution grid and a slightly smoother density mapping. The SM equatorial mapped measured image is not shown.

No Smoothing, No Decimation, Rectangular

The set of three figures below show output for an identical run as that producing figure 1 except that the solution grid is stored in a rectangular coordinate system. The SM equatoral remapping of the measured image has been omitted.

Zero Matrix, Smoothed and Raw Solution Matrices

The figure below shows the a Zero solution matrix. Since the inputs to the matrix are either 0 or 1 the color scaling has been set so that 1 is above the maximum and zero below the minimum. The dark portion of the plot are the regions where there is a possible He+ density.

Smoothed 5x5L Inversion Map

The figure below shows is a plot of the plasmasphere He+ denisty mapping which has been smoothed using a 5x5L filter. The plot is undecimated.

Radial Cut Plots

The figure below shows a set of radial cuts through the above inversion map. The cut Start, Stop, and Delta options were set to 0, 24, and 6 respectively. The MLT corresponding to each line trace can be estimated using its color and the color bar to the right.

Gradient Plots

Radial (top) and azimuthal (bottom) gradient plots.
