... 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. ...

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. ...

... We demonstrate through numerical simulations that model parameters estimated with our technique are essentially bias-free, even when the average number of counts per bin is 1. ... The IW technique avoids such biases by estimating through successive iterations, where for each iteration, j, , and the best-fit parameters are determined by minimization of . ... In our sample, we find that the minimum values and best-fit parameters converge after about 6 iterations. ...

Estimating the NEO Population and Impact Risk: Past, Present and Future . ... Since most of the risk resides in the largest impactors, finding that fraction of the largest bodies, and that none of them has a significant chance of impacting in the next century or so, "retires" more than 90 % of the impact risk, including most of the risk of a globally catastrophic impact event. ... In the mid-size range, from ~150 m to ~1 km, the main risk is from tsunami generated by an ocean impact. ...

... Several attempts to discover the FICN signal in VLBI nutation series made during last years failed. ... We investigated several VLBI CPO series by means of spectral and wavelet analysis. It has been shown that there are several periodic signals with close amplitude around the expected FICN period without any prevailing one that can be reliably associated with the FICN. ... DATA ANALYSIS We analyzed several CPO series obtained in IVS analysis centers by means of spectral and wavelet analysis. ...

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. ...

... solar system . ... Comet dust reveals unexpected mixing of solar system . ... Chemical clues from a comet's halo are challenging common views about the history and evolution of the solar system and showing it may be more mixed-up than previously thought. A new analysis of dust from Comet Wild 2, collected in 2004 by NASA's Stardust mission, has revealed an oxygen isotope signature that suggests an unexpected mingling of rocky material between the center and edges of the solar system. ...
