We present a catalogue of the kinematic properties of Coronal Mass Ejections (CMEs) produced by applying geometric fitting techniques to CMEs observed by the Heliospheric Imagers (HIs) on-board both NASA STEREO spacecraft as part of the EU FP7 HELCATS (Heliospheric Cataloguing, Analysis and Techniques Service) project. The catalogue builds on previous HELCATS work in which 1901 CMEs were identified in HI observations throughout the operational phase of the STEREO mission; 2007-2014. Time-elongation plots are used to track a subset of these CMEs and geometrical models are then applied to determine their speeds, propagation directions and launch times. This new catalogue contains a total of 1353 CMEs, 699 from STEREO-A and 654 from STEREO-B. A further subset of CMEs is identified, which are observable by both spacecraft, and stereoscopic fitting techniques are applied. The statistical properties of the catalogues are discussed and the results compared with those from existing CME catalogues during the same period.
