Effelsberg has station name 'EB_VLBA' Arecibo has station name 'ARECIBO' GBT has station name 'GBT_VLBA' The phased VLA has station name 'VLA27' The SCHED manual can be read on the WWW at: http://www.aoc.nrao.edu/~cwalker/sched/sched/sched.html 3) Arecibo and Effelsberg do not support automatic tape allocation.
Furthermore, Effelsberg has only 1 recorder, so an observing gap of 10 minutes is necessary to allow for tape changes (see the HSA at EB document at http://www.mpifr-bonn.mpg.de/EVN/HSA-EB for more information).
Be aware that if the last tape pass is not recorded continuously, but involves intermediate stopping of the tape, then a feature of the NRAO scheduling software executes a "post-pass" forward and reverse winding of the tape.

 NRAO: High Sensitivity Array
By adding the GBT, phased VLA, Arecibo, and Effelsberg to a VLBA experiment the sensitivity can be increased by an order of magnitude (see figure at left showing sensitivities for a 1 hour integration recording at 256 Mbps).
Effelsberg has often been used in conjunction with the VLBA, and is frequency agile at 5 GHz and above.

This report lists a number of developments at the Effelsberg 100m telescope since the last Working Group meeting which may be of relevance for geodetic VLBI observing.
Bug fixes and new facilities such as barrel roll were successfully tested in a geodetic VLBI experiment correlated in Bonn.
Work continues on both the water vapour radiometer and the plans for installing a GPS receiver in Effelsberg, for providing auxiliary phase and delay measurements for VLBI.

 Max Planck Institute for Radio Astronomy, Bonn - Radio Telescope Effelsberg
With a diameter of 100 meters, the Radio Telescope Effelsberg is one of the largest fully steerable radio telescopes on earth.
The telescope is employed to observe pulsars, cold gas- and dust clusters, the sites of star formation, jets of matter emitted by fl holes and the nuclei (centres) of distant far-off galaxies.
Effelsberg is an important part of the worldwide network of radio telescopes.

After 4 days the standard fireball models predict a size for the afterglow of just 10e17 cm or 0.01 mas, but still large enough to begin quenching the scintillation as confirmed in the second VLBI epoch 7 days after the burst.
A third VLBI epoch including Effelsberg and going to 22 GHz to maximize resolution measured the size of the afterglow to be 0.08 mas 24 days after the burst.
The observing frequency was again 8.4 GHz, and the size predicted by the standard fireball model was 0.2 mas.

 L-Band Wide Observations   (Site not responding. Last check: 2007-10-28)
The Effelsberg Mid-latitude survey image of polarised intensity in the same area is shown below the Arecibo image.
Therefore there is an arbitrary rotation of the polarisation position angle difference between the Effelsberg and Arecibo images.
However, the polarisation features in the Effelsberg image are seen in the L-band wide data with higher angular resolution, showing, for instance the structure of the dark lanes surrounding the strong source near the centre of the image.

Arecibo is much larger, but Effelsberg is fully movable while Arecibo is just built into the ground.
Iirc Effelsberg is the second largest in the world of its kind and indeed it looks pretty impressive.
Effelsberg is the largest moveable radio telescope in the world, the one in Puerto Rico is the largest non-moveable radio telescope.

 :: LOFAR - General Information
At the end of October 2005, the Max-Planck-Society granted funding for a LOFAR antenna station in Effelsberg (the radio observatory of the Max-Planck-Institut für Radioastronomie (MPIfR) in Bonn).
Together with an earlier pledge to provide a wide band data transport link to the observatory, the expansion of the LOFAR network outside the Netherlands is becoming reality.
A plan for a total twelve LOFAR stations at sites in Germany - of which six are planned in more detail already - met an enthusiastic response at the annual autumn meeting of the Astronomische Gesellschaft in Cologne at the end of September 2005.

 The Effelsberg 6 cm Survey of the Galactic plane
A survey of the galactic plane has been made with the Effelsberg 100-m telescope at a frequency of 4.875 GHz with a beamwidth of 2.6'.
The data are presented as radio contour maps covering l=357.5 to 60^o, b=+-1^o, together a list of 1186 radio sources.
We therefore did not de-convolve the apparent diameters, or estimate integrated fluxes for the sources.

Relevant deadlines are also mentioned, as are how to use the vlbiobs account at the Array Operations Center (AOC) and how to monitor the VLBA's actions during your program.
Effelsberg has only 1 tape drive, so automatic tape allocation is not practical; for that station you *must* allow a tape change gap of 10-15 minutes and follow the tape management advice in The Sched User Manual (see section 5) concerning tape usage and postpass avoidance.
The phased VLA has special calibration needs; you can ensure that these needs are met if you use the scheduling program sched (see section 5) to make your VLA schedule files.

 Radio Observations of the Great Comet Crash
When it became obvious that comet P/Shoemaker-Levy 9 would impact Jupiter in July 1994 the Effelsberg 100 m radio telescope of the Max-Planck-Institut für Radioastronomie became a key link in a world-wide network of radio telescopes to monitor this unique event.
Full polarization measurements of the Jovian radio emission were performed at Effelsberg before, during and after the impacts at three different wavelengths (frequencies): 2.8 cm (10.55 GHz), 6.3 cm (4.75 GHz) and 11.1 cm (2.695 GHz).
In Figure 3 the evaluation of the nonthermal flux density during the whole impact week is shown for 11 cm and 6 cm wavelength as a function of universal time UT. The times of impacts during the Effelsberg view periods are marked with a vertical arrow and the corresponding name of the fragment.
