This file gives some hints on setting up the ABPP for pulsar observations and taking data. ... ABPP will always choose the largest bandwidth possible given the RF and the DM of the pulsar. ... The simplest way to control the WAPP datataking program is via tha datataking GUI shown below. ... As soon as the PC echos back to the gui in the ABPP LOG, that it is, in fact, taking data, you will see this reflected in the gui by the pink "SETTING UP MACHINE" being replaced by a green "DATATAKING ACTIVE". ...

ATNF ATUC Memorandum To: ATUC From: Bob Sault Date: 22 November 2004 Subject 3mm systems on the ATCA Summary of 2004 The highlight of the year at the ATCA has been the installation of the 3mm systems on 5 antennas. ... This was appreciably later than the originally scheduled 6 July start to the 3mm season, and was caused by some substantial engineering challenges in the local oscillator system near the end of the project. ... It is unlikely that this will be resolved by the 2005 season. ... Pointing | ...

Detector on-chip integration (DIT): seconds. to your chosen value - a separate page gives recommended values to use for DIT - for modes 1 and 2 below you may wish to start with the maximum recommended values as these will minimize the effect of read noise (a total object exposure of Y secs with DIT=X secs will produce Y/X lots of read noise) and give you a lower limit on the time needed. ...

The Linear Ramp Filters (LRFs) provide a narrow band ( ) imaging capability which is continuously tunable from 3710е to 9762е. These are essentially a collection of narrow band interference filters whose central wavelength varies with position on the filter glass. ... If it is necessary to know which CCD will be used, observers can consult Table 3.7 or Table 3.8 , or use the on-line LRF calculator tool on the WFPC2 WWW pages. ...

The Earth's passage right through the centre of trails is associated with the most spectacular meteor displays (studies show that, as well as how close to the centre of the trail you are, the strength of the display also depends on how far along a trail's length you are). ... The encounter with the 1932 trail will lead to enhanced meteor activity: a nice outburst, but below storm level. ...

Comet Pojmanski , officially designated C/2006 A1 and discovered only in January, now sports a turquoise tail several times longer than the full moon. Comet Pojmanski 's ion tail is due to gas particles expelled by the comet being pushed away from the Sun by the solar wind , the same wind that ionizes gas in the tail causing its blue tint. ...
