|
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.
In order to apply for DDT a brief proposal should be prepared using the template
provided. The proposal should contain a concise summary of the
scientific justification and should not exceed some 20 lines of text.
Time requested should not exceed, in principle, 3 hours per single
observation. DDT proposals should be submitted not later than 3 weeks
before the desired scheduling of the observations.
Publications which
result or which are partly based on observations carried out during DDT
should be acknowledged as follows:

Applications for Director's Discretionary Time (DDT) at the 3.5m and
2.2m 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.
