  • Maximum grey values (gaussian peak values) are randomized - can result in star not appearing in output.
  • Example output: (100x100 pixel canvas, 0-100 grey value range, 10 stars)

  • Simulation generates stars with random positions.
  • Canvas size and no. of stars are variable.
  • No gaussian profile for stars or grey values (pixel value is either 0 or 1).

Improvement - Gaussian star profiles (05/10/2016): Simulation_test2.py.txt

  • Generated stars now have 2d gaussian profiles.
  • Maximum grey values (gaussian peak values) are randomized - can result in star not appearing in output.
  • Example output: (100x100 pixel canvas, 0-100 grey value range, 10 stars)
