Abstract :
Realta is the real-time analyzer of MEGAlib, a software tool to simulate and analyze the data from soft-to-medium-energy gamma-ray detectors in space and on the ground. Realta encompasses the complete data analysis path which ranges from coincidence determination, Compton scatter and pair creation event reconstruction, event selection, image reconstruction to spectral identification. Realta is highly multi-threaded to fully utilize today´s multi-core CPUs and to enable real-time processing. Taking advantage of the versatility of MEGAlib, Realta can be applied to a wide variety of gamma-ray detectors (pixel detectors, strip detectors) and measurement scenarios (near field 2D and 3D, far field). Realta and MEGAlib are open source, freely available, written in C++, and based on ROOT.
