... 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. ...

... Both sets of objective transmission gratings consist of hundreds of co-aligned facets mounted to supporting structures on 4 annuli (one for each of the four co-aligned mirror pairs) to intercept the x rays exiting the HRMA. ... The two sets of transmission gratings, attached to the mounting structure are shown in Figure . ... An individual facet has 0.43-m-thick gold grating bars with 50% filling factor and 9920- period, resulting in 1.15-/mm dispersion. The HRC-S is the primary LETG readout. ...

Next: 2--Dimensional Images Up: Test Data Previous: Test Data . Modern solid-state detectors produce data which differ in two main aspects from classical photographic images: (a) a much higher S/N (signal to noise ratio) and (b) the rigid spatial digitisation of the incoming flux. ... The usage of the programs and images that we provide as a reference test package should also facilitate documentation of possible application software malfunctions and their subsequent repair. ...

The NIFS layout is based on the realisation that significant cost savings will arise from packaging NIFS in an identical container to that used for NIRI. NIRI is the near-infrared imager being constructed by the University of Hawaii for Gemini North. ... The NIFS integral-field spectrograph will replace the NIRI camera on this face. ... The OIWFS will use a Rockwell 1024 1024 detector and an SDSU-2 detector controller , as does NIRI. ...
