The idea is to commission WFTP on the 0.5 m-telescope of the Observatory at the Lustbühel in Graz (OLG), Austria. The geographic coordinates are N47°04'02", E15°29'37". The sky-brightness at the site is 20 mag/". The first science verification of WFTP will be already obtained with this telescope. An important feature of the OLG is that it is operated fully remotely. The operation of WFTP can thus be fully tested and commissioned while mounted at the OLG.
After the commissioning WFTP will be transfered to the 0.9 m-telescope of the Observatorio de Sierra Nevada (OSN), Spain. The geographic coordinates are N37°02'51", W03°23'05". This site has a well developed infrastructure and superb weather conditions. The average seeing is 0.67" and observations can be carried out in 60-80% of the nights. Out of these nights, 50%-60% are at least partly photometric and typically 25% are fully photometric.
In the future it will also be possible to use WFTP on any other medium-sized telescope, e.g., on the Canary Islands or at La Silla. Although the S/N-ratio is higher on larger telescopes, the FOV is smaller and we would have less comparison stars. Thus, the 0.9 m-telescope is ideally suited to achieve our science goals. Also with respect to the available time and the large amount of observing time needed for our program, the 0.9m-telescope at OSN is ideal.
