     Analysis
    • Ran a median filter (i.e. finding median of a box, size n, centered on each pixel) for different box sizes, on the simulated background+stars.
    • Subtracted the median image from original, to remove background. Then created histograms of resulting pixel values.

    Analysis
    • Ran a median filter (i.e. finding median of a box, size n, centered on each pixel) for different box sizes, on the simulated background+stars.
    • Subtracted the median image from original, to remove background. Then created histograms of resulting pixel values.
    • Histograms assumed to be gaussian - found sigma and mean for each.
    • Plotted sigmas and means in relation to box size.

    Simulation:

    • Made example star field with no background (used M103 data).
    • Modified simulation to generate position-varying background. Mean and standard deviation can be changed independantly.
    • For testing, generated means and standard deviations using following functions ('inclined planes'):
      • Mean = 900 + (0.5)x + (0.005)y
      • S.D. = 5 + (0.01)x + (0.01)y
      • x,y = pixel positions
    • (Can also generate with more complicated functions - e.g. taylor expansion)
    • Used mean and S.D. per pixel to generate random gaussian distributed value for background, added to example star field.
