... This document and the attached postscript figure document an analysis that I did to determine the optimum midpoint and required ranges for both the rotator and azimuth for the 2.5 M telescope. ... I simulate a series of drift scans on the sky for tracks that cover the northern survey area. These tracks cover the range in survey latitude of -60 to +60 degrees, spaced by 10 degrees. ... Along each track the azimuth, elevation, and position angle of the CCD is computed at 1 minute intervals. ...

... Armagh Observatory reports that December was much colder, sunnier and drier than average. The mean monthly temperature was тАУ0.3 degrees Celsius (31.4 degrees Fahrenheit), about 5.4 Celsius below average, making December 2010 the second coldest December in Armagh since records began around 1795. The three coldest Decembers in Armagh are now those of 1878, 2010 and 1796 , with average temperatures of -0.5 C, -0.3 C and 0.6 C respectively. ...

... Bad Astronomy . ... Bad Astronomy : The seasons are caused by the change in the distance of the Earth to the Sun. ... The change in distance of the Earth to the Sun is a very minor player. ... Well, not completely wrong; certainly the Earth's distance from the Sun has something to do with the temperature, but it is a relatively minor effect. ... Basically, the temperature depends only weakly on distance changes; the temperature goes as the inverse square root of the distance of the planet to the Sun...

Next: Conversion Up: Polarisation Previous: Polarisation Index .
