... 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. ...

... We considered our current level of technology compared to that of an average alien civilization.

For today's in class we will be working with spatial and temporal data sets which are quite noisy. Particularly, you have monthly rainfall totals for the following six locations in Oregon from the period 1950 - 1999. Eugene . Salem . Portland . Astoria . North Bend . Newport . There are many facets of what you can do with this data. Please explore the following questions with some degree of sound statistical reasoning and data presentation: .

Abstract: The calculation of flux upper limits in the source-free ("background") regions of photon-limited images is complicated by instrumental and statistical modeling and requires non-trivial computational effort. ... The principal component in this is the time taken to pre-process and handle the 30 GB of RASS data rather than the calculation of each upper limit. ...

... The hotter the gas, the faster they move, and the more energy each of them holds. The free ions and electrons in a plasma behave the same way. Knowing the temperature of the high atmosphere of Earth, or that of the Sun, we can calculate energies expected of ions and electrons found there. However, ions and electrons actually observed in space are often much , much more energetic, and may move at a respectable fraction of the velocity of light (300,000 km/sec or 186,000 miles/sec). ...

... It is reasonable to expect a priori that the evolution of events is strongly time dependent, so the star formation history in a galaxy is another important parameter. Therefore, by calculating the evolution of events after a -function like star formation burst,   one gets a Green function for any arbitrary star formation history. ... The source evolution in a galaxy with given star formation rate is thus calculated as . ...
