Note that (a) and (b) will occur for transversal waves, whereas (b) and (c) will occur for sound waves. For cases (a) and (c) allowed wavelengths are λ = 2 L n, whereas for case (b), allowed wavelengths are λ = 4 L ( 2 n − 1). WebJul 10, 2024 · We compared the performance in the V-band of neural networks for a 3.6-m telescope and found that the “ResNet” gave the best results. The best wavefront residual RMS obtained for guide star magnitude 4 to 8 and r0 = 0.3 m r 0 = 0.3 m was 123 nm for wide-band PSFs over the wavelengths 470 to 700 nm. ebay computer parts laptop
