A short
description of how the PKE works
1. Duties
- scientific evaluation of observing programs;
- recommendation to the directors, stating scientific
value (graded
in
three
priority ratings or in a rejection), time required for completion of a
project.
2. Protection of Priority
- Observing requests are only considered by the
committee if the
receiving system required is already in operation or will be ready
within the
coming 6 months.
- In principal, for similar projects the observing time
should only be granted once.
- An observing project is protected for a period of one
year after completion of the observations.
- Overlapping programs will be coordinated by the
Directors before observing time is allocated.
Members
of the Program Comittee for Effelsberg
The present members of the PKE are:
David Champion (MPIfR),
Jochen Heidt (LSW Heidelberg),
Gemma Jansen (Jodrell Bank Observatory),
Uli Klein (Bonn University),
Karl-Heinz Mack (INAF Bologna),
Richard Porcas (MPIfR),
Andrea Tarchi (INAF Cagliari),
and Helmut Wiesemeyer (MPIfR).
Allocation
of
Observing
Time
Observing time is allocated on the basis of sequence of receivers
scheduled
on the telescope, and, basically, in the order of the priorities
recommended
by the program committee.
Special consideration is given to:
- VLBI network sessions, which amount to some 30% of
the total
observing
time, and are reviewed by a special program committee.
- Observations which are directly related to
dissertations from
German
universities.
- Observations which require specific dates, such as
time critical
observations
of transient phenomena and/or observations that are part of
multiwavelength
campaigns requiring simultaneous observations with different telescopes.
In spite of a positive recommendation by the PKE, scheduling of a
program
may be delayed since:
- the number of approved proposals exceeds the
available observing
time.
(This is particularly the case for observations at 1.3 cm wavelength.)
- the requested receiver is not ready for installation
at the time,
or
its
installation is not planned. (One should bear in mind that receivers
for
the telescope cover a range from 3 mm to 75 cm wavelength.)
An observer can therefore not judge when the observing time will be
allocated,
simply on the basis of the PKE recommendation. He/she will usually be
informed
about 4 weeks in advance when the project is to be scheduled.
All refereed proposals remain eligible for one year.
After
this,
they are removed from the waiting list. The observer will be informed
on
this act and may resubmit his proposal to the PKE. (On average, 25% of
all proposals are affected by this rule.)
In case
you observe
at
Effelsberg for the first time, it would be a good idea to contact a
local astronomer:
