Simulated Test Data

Fig. 1 is an 800800 simulated PC image used to test the restoration algorithms. It contains 2500 stars with a magnitude distribution shown in Fig. 2. The image was constructed using a Tiny TIM PSF at a wavelength of 4000 Å and a pixel size of 1/5 the size of the PC pixels. This sub-sampled PSF allows us to simulate stars with positions that are not required to be at the center of a pixel. We added both Poisson and read-out noise to the image to simulate the noise statistics expected when two PC images with 25 sec exposures (filter F439W) are co-added.
