Applications for Director's Discretionary Time (DDT) at the 3.5 m and 2.2 m Calar Alto Telescopes are invited. The goal of DDT allocation is to provide fast access to the telescopes in order to perform new and innovative science for which the regular scheduling procedures may be too slow or to supply critical but short observations for existing programs, which could not be obtained during regular observing runs. An average of 1.5 nights of DDT is available per month and per telescope, to be scheduled during Service Mode blocks.
Instruments for which DDT can be applied are preferably those ones mounted during the service blocks (see the current Schedule). Generally no additional instrument changes will be made. However, due to the flexible scheduling within the service blocks it cannot always be guaranteed that the desired instrument finally is available.
