... Bad Astronomy . ... I think I will break from my usual format of Bad Astronomy/ Good Astronomy by saying that the way we define seasons currently is not strictly bad, but I feel (in my opinion!) that it could be better. The definition of when the seasons begin is at the moment of solstice or equinox; that is, winter (in the north) starts on December 22 nd and summer starts on June 22 nd . ... Now imagine breaking up the Sun's 46 degree up-and-down yearly swing into 1 day intervals. ...

... With enough velocity, a spacecraft can break loose from the Earth's gravity and enter an orbit around the Sun, like that of a planet. If it then orbits the Sun with the same period as the Earth--one year--it may keep a fixed position relative to Earth. ... If the distance is just right--about 4 times the distance to the Moon or 1/100 the distance to the Sun--the spacecraft, too, will need just one year to go around the Sun, and will keep its position between the Sun and the Earth. ...

... The shape and width of observed PSFs varies slightly over time, due to the change in focus of the telescope. The focus variation consists of two terms: a secular change, due to the ongoing shrinkage of the Metering Truss Assembly, at a currently estimated rate of 0.85 mm month-1, and short-term variations, typically on an orbital time-scale (the so-called "breathing" of the telescope). ... a(1 pix) = 0.0338 +/- 0.0038 . ...

... POLYNOM MAP NO | POLYNOM MAP2 NO 2 Changes The new distortion map is based in observations of the G153 eld. ... The previous map had been obtained by tting the measured o set (distorted position minus linear position, or detector minus sky positions) as a polynomial function of the linear (sky) position. ... Therefore what is needed is a function of the measured detector (distorted) position and this is how the new distortion map OM ASTROMET 0010 has been built. ...

The Telescope:Pointing Data script takes set of pointing error measurements of pointing reference stars across the sky. ... To retry measuring the star, fix the problem (e.g. by adjusting focus, exposure time or offset) and press Continue . ... For each point in the az/alt grid the script will find and slew to a nearby pointing reference star, measure the star, write the pointing error to a data file whose path is displayed, and correct the pointing error. ...
