The strongest sources of RFI are mobile phone towers, satellites and TV transmitters, all of which are relatively stable in time. Two surveys atcom au-210 shown, one from and the other from The licenses applicable to each frequency range are shown as coloured regions, labelled with a similar colour at the top of the plot.

An RFI monitoring antenna sits atop the central control building at the observatory. It monitors the atcom au-210 range - MHz once every 20 seconds, with 2 MHz frequency resolution, and presents its data in near-real time on a web page. The waterfall plot is useful for seeing emission switch on or off over the last hour. All data from the RFI monitor is archived, and if you want to get the output of the monitor for a particular time range since its installation in Novemberplease visit the archive query page. Because of the strength of atcom au-210 RFI, it can often drive the front-end system of the 16cm receivers, or the CABB digitisers, into saturation; if this occurs, the data becomes unusable.

We do now sometimes receive advanced warning on when this RFI may be present, and if this will affect observations, the investigators will be notified so they can plan how to atcom au-210 with it. Only the 16cm band is affected by mid-week RFI, so if mid-week RFI is forecast during your observations, you may wish atcom au-210 avoid using the 16cm band during those times, wherever possible.

If this is not possible, you may ask for a schedule swap, but this may not always be a possibility. Our observations have also shown that mid-week RFI is present only for a small fraction of the default CABB 10 second cycle time, but is so strong that it ruins the entire integration. You may therefore be able to cope with mid-week RFI by running with a shorter cycle time say 1 or 2 seconds and flagging those cycles in which the RFI is present; this will result in atcom au-210 much higher data rate of course, and is only really suitable for continuum experiments that do not need mosaicking. The RFI present in the 4cm band is direction dependent, and can be quite variable over time. Using a similar survey technique to the 16cm band, where the fringe-rotation is disabled, we can determine the static levels of RFI.

We expect that signals coming from satellites will be stronger towards the celestial equator.

The 4cm band, as atcom au-210 during an RFI survey fromwhile the antennas were pointing at the celestial equator at transit. Indeed, we see that in the pink- and orange-highlighted regions of those two figures, the signal intensity is higher while pointing at the equator. That is, in the frequency bands licenced for satellite communications to Earth, the ATCA will see a lot more interfering signal while observing near to the equator.

Frequency atcom au-210 of satellite emission bands observed with a 4cm RFI survey. The ranges given are delimited by ACMA allocations, so several entries may be given even if they represent one contiguous frequency range.

There appears to be no significant interference within the 7mm and 3mm bands. The 15mm band, as observed during an RFI survey fromwhile the antennas were pointing at the celestial equator atcom au-210 transit.

These ranges are A subset of the 15mm band, as observed during an RFI survey fromwhile the antennas were pointing at the atcom au-210 equator. This geostationary satellite is at an azimuth of This position is approximately If you are worried about this interference and wish to avoid it, we recommend atcom au-210 new set of continuum central frequencies of It is recommended to specify in your proposal dates that are not suitable for observations if the Sun angle is too small.

atcom au-210 Low-frequency observations, particularly in spectral-line mode, should be made at greater Solar separations. You are advised to observe at night in cases where atcom au-210 quality 21cm HI data is essential on the shortest 30m baseline. For spectral-line observations, software exists in Miriad to model and subtract out solar interference.


Some information about solar activity can be obtained from the Ionospheric Prediction Service. A synthesis imaging telescope such as the Compact Array provides a great deal of flexibility when deciding how to image an object. In addition to the well-known trade-off between atcom au-210 time and sensitivity, we have trade-offs with maximum resolution and with the sampling interval atcom au-210 the visibility plane. The choice of angular resolution is fairly straightforward.

The choice of u,v -plane coverage is more difficult. The amount of independent information needed to specify the image should not exceed the number atcom au-210 independent u,v -plane samples. At one extreme, consider making a high resolution image of a complex source filling the entire primary atcom au-210.
