Differences in conditions from Tape's simulations
  Wavelength Tape randomly chooses wavelengths from "green" to "red". The HaloSim simulations are for a single wavelength of 577 nm.   Some of Tape's arcs are therefore broader, particularly those where light is refracted between faces with an interfacial angle of 90°.

  c/a ratio Tape uses an unspecified distribution of c/a ratios about the mean. HaloSim uses a single fixed c/a ratio.

  Solar disk HaloSim uses a point source. walter Tape uses an 0.5° diameter solar disk.
Presentation A very high resolution screen would be needed to reproduce Tape's printed simulations in two-level "black dots on white" simulations. These HaloSim simulations use an 8 level grey scale to best match Tape's printed pages.
