Duty astronomers at the Compact Array are rostered from ATNF staff and students to provide support to observers at Narrabri for periods of one week at a time. The duty astronomers are required to assist observers prepare observing schedules, help set up the Compact Array at the start of an observing run, diagnose and attempt to solve problems that arise in the course of the observations and help observers with the initial analysis of their data. ... www.atnf.csiro.au/observers/tidbinbilla . ...

No problems were encountered. ... The proposal completed with no reported problems. ... There were no reported problems. ...

... In this activity, students will observe that the faintest stars which they can see in the sky are affected by many things: the adaptation of their eyes to the dark, the presence of clouds or haze, the time of year, and the presence of light pollution. General Information . ... After completing this activity, students should have a better understanding of the practical processes for dealing with the light pollution problem and with other environmental and societal issues. << previous page | ...

The spectral line gui allows you to setup the wapps for 1 polarization per board. You can select polA or polB for the first board and the opposite pol for the 2nd board. This allows for more channels per spectra (but uses up more boards). ... Brd 1: 3 level auto correlation, polA. ... The problem is that the gui configures the wapps to provide polA to both boards (actually it could be polB, i'm not really sure... the important thing is that you only get 1 polarization). ...

... Using the self-consistent 3D hydrodynamical code in Kobayashi et al. (2007) , we simulate the star formation and chemical enrichment history of the Universe. ... We also predict the rates of supernovae and gamma-ray bursts, and the properties of the host galaxies, which will be observed with the ANU's new SkyMapper telescope. ... Supernova feedback on galaxy formation. ... Feedback from active-galactic nuclei (AGN). ... COALA : Universe Galaxy AGN Star Planet ...

The problem of solar wind data correlation for the observations onboard several spacecraft is very important for three points of view: . ... This problem is studied now in detail by systematic determination of ion flux and ion velocity data correlations by INTERBALL-1 (IKI group), WIND and IMP 8 (both - MIT group). ... Solar wind plasma correlation lengths from IMP 8, WIND and INTERBALL-1. ... Correlation of solar wind observations onboard several spacecraft: INTERBALL-1, IMP 8 and WIND data. ...

We cannot observe the way the distant universe accelerates cosmic rays or produces energetic photons, but acceleration processes also occur on our Sun , though on a much more moderate scale. ... That is why such events are often missed by cosmic ray detectors near the equator, where the lowest energies are excluded by the Earth's magnetic field. The best detectors for observing solar particles are therefore those sensitive to the lowest energies of the cosmic radiation. ...

If you select this entry option (Default) you can provide the revolution range for which the visibility should be computed. ... A time is specified for the minimum length that a target is required to be visible. ... The visibility tool imposes that for a target to be visible, all corners of the corresponding bin must be visible. ...

Next: Nonlinearity Up: Special problems Previous: Special problems . Because a full set of colors is required to account for color terms, it is not possible to reduce data for stars that have not been observed in all filters. If you have some stars that were observed in only a subset of bands, you should extract from the entire table of observations just the subset of bands, and run the whole set of stars in this band subset to obtain reduced values for the stars with incomplete observations. ...

The REMOT project objective is to develop and validate a generic approach to allow remote control of scientific experiments and facilities that require real time operation and multimedia information feedback. ... These have been partly implemented to perform a set of demonstrations, showing the feasibility of the design. ... Integrating the control system of the Galileo telescope in the REMOT project is simple: . ...
