... These are ``quirks'' rather than ``bugs''. Below is a list of quirks. When loading a file and ``Reset Intensity Upon File Load'' is disabled, the intensity range of the previous image will be used. ... When moving between two images (such as when blinking, or when loading a new image), the display system attempts to retain the old image parameters (i.e. zoom box). What is retained are the corners of the zoom box measured in image pixel co-ordinates, not world co-ordinates. ...

Trail encounter . ... Expected meteor rates . ... The Leonids are the debris of Comet 55P/Tempel-Tuttle. ... 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. ...

Next Previous Contents . This means that an interrupt happened that no driver expected. ... In many cases you can safely ignore this error message, especially if it only happens once or twice at boot-time. For boot-time messages, look at the messages which are nearby for a clue as to what is going on. For example, if probing is going on, perhaps a probe for a physical device caused that device to issue an interrupt that the driver didn't expect. ...

The first stars, known as Population III, produced the first heavy elements, thereby enriching their surrounding pristine gas. However, all previous detections of metals in intergalactic gas clouds find a heavy element enrichment at least 1/1000 times that of the solar environment, which is higher than expected for remnants of Population III stars. ... Finally, I will summarise the prospects for finding similar systems in future surveys. ...

... Anticipated Radiation Effects . ... Various radiation effects can be anticipated, based on similarities to other CMOS devices. ... Total dose radiation effects in CMOS devices can be divided into two broad classes: charge trapping and interface state generation. ... When interface states are located in a depletion region, they act as sources of dark current. Increased dark current is expected to be the dominant radiation effect in active pixel sensors, leading to increased shot noise. ...
