CosmoSim Roulette Statistics

• Purpose explore the effect of changes in roulette amplitudes

• Two different tests

  • descriptive statistics

  • tweaking amplitudes

Descriptive statistics¶

• Directory Test/roulettestatistics

./datasetgen.sh
./test.sh
pdflaex report.tex

The resulting PDF file shows the mean and standard deviation of the roulette amplitudes over 4000 images

Tweaking amplitudes (legacy)¶

./raytrace.sh
./tweak.sh
./txt.py
pdflatex tweak.tex

The resulting PDF report shows several simulations of the same lens and source, tweaking different fifth order amplitudes. The ten first images in the dataset are used.

Tweaking amplitudes¶

• Directory Test/tweak2

./tweak.sh

The resulting PDF report shows several simulations of the same lens and source, tweaking different fifth order amplitudes. The ten first images in the dataset are used.

This test uses a special selection of lens/source configuration, instead of the random selection in the other tests.
