Next: Combining Flat Fields Up: Preparing Your Calibration Previous: Combining Bias Frames . Similarly to the bias combination one can obtain an average dark current frame. However, one should consider whether the dark correction should really be applied: one needs a reasonable number of dark frames in order not to degrade the S/N, and obviously this takes telescope time. ... In that case, provided a good linearity of the CCD, one could do with the subtraction of an average dark frame. ...

... Archives . ... If getting the first derivative (score function) and the second derivative (empirical Fisher information) of a (pseudo) likelihood function is feasible and checking regularity conditions is viable, a test for global maximum (Li and Jiang, JASA, 1999, Vol. 94, pp. 847-854) seems to be a useful reference for verifying the best fit solution. I didn?t see any ways to confirm that best fit results from XSPEC or Sherpa are a global maximum without searching whole parameter space. ...

Hubble Observations Shed New Light on Jupiter Collision . Was it a comet or an asteroid? ... Their initial findings, combined with results from other space-borne and ground-based telescopes, shed new light on Jupiter's atmospheric winds, its immense magnetic field, the mysterious dark debris from the impacts, and the composition of the doomed comet itself. ... Hubble's ultraviolet observations show the motion of very fine impact debris particles now suspended high in Jupiter's atmosphere. ...

... Polar plumes appear in images of the Sun's corona as faint linear enhancements in radial directions emanating from the North and South polar regions during the period of minimal solar activity. ... What are polar plumes? ... Even if plumes seems to be in rigid body rotation with the solar magnetic field, classic inversion with Radon transform is unable to reconstruct such 3-D structure due mainly to transient phenomena. ... We address points 2) and 3), solved with projective techniques. ...

. The figure shows an image of Mercury's surface (left: obtained using publicly available mosaic of Mercury from the MESSENGER spacecraft and a color-coded view of the global crater areal density (right), obtained by measuring craters greater than 15 miles (25 kilometers). The region within the white line corresponds to the heavily cratered terrains analyzed to calculate the age of the oldest surfaces on Mercury. // Johns Hopkins APL

... Measurements of global temperature by themselves are indeed a poor way to establish temperature trends because 1) the data are intrinsically noisy and 2) the global mean temperature is physically imprecise. P> However, when one measures temperature trends as a function of latitude, the predicted increases at latitudes above +/- 45 degrees are clearly seen. ... This latitude data caused a Sept. ... P> Furthermore, global warming is a far more complex issue than simple temperature increases. ...

... An analysis of series of flat­field exposures obtained in echelle mode adds support to the view that the performance of an instrument should be monitored closely and described quantitatively. ... This may result in confusion about basic instru­ mental parameters, the precision of the set­up, the amount and distribution of calibration frames which are required and finally the assumptions on which the data reduction procedure should rely. ... The value for pure random noise is indicated 1). ...
