Stereo Reconstruction for the early days of CTA — •Lukas Nickel, Richard Wiemann, and Maximilian Nöthe for the CTA collaboration — TU Dortmund

The Cherenkov Telescope Array(CTA) aims to increase sensitivity for gamma-ray astronomy compared to the currently operating experiments H.E.S.S, MAGIC and VERITAS while operating as an open observatory. Low-level analysis will be performed with the framework 'ctapipe' that is currently in active development.

The two arrays are planned to consist of 19 (La Palma) and 99 (Chile) telescopes. With these huge numbers of telescopes geometric reconstruction methods for the source position become far superior over traditional disp-based methods.

However, these methods require a certain amount of telescopes to perform well and it is going to take several years to build the complete array. This contribution aims to show that the disp-based approach using the 'aict-tools' works for mono CTA-analysis and the resulting stereoskopic results outperform the geometric approach for low multiplicity events.
