... badpixfind searches for pixels identified as containing no useful data, and uses this information to produce an output file. ... A bad pixel map (or mask) can also be produced. An important point regarding the bad pixels is that there are essentially three separate (though not exclusive) sets of bad pixels that must be dealt with. ... The user is able to specify maximum and minimum allowed values (via the parameters lothresh and hithresh ) to screen for hot and dead pixels. ...

Next: Combine Example Up: Preparing Your Calibration Previous: Combining Flat Fields . The procedure is similar to the flat field combining procedure, except that you may want to scale the sky level using the mean, median or the mode of the intensity distribution or taking into accoun the exposure time. Hence, in the combining, like in the case of combining flat fields, correct weighting of the frame is important. ... Table: Keywords for combining sky calibration frames . ...

FAMILIES AND SCATTERING . ... An important observation on the orbital distribution of irregular satellites is that satellite families at Saturn, Uranus and Neptune are not well defined. At Jupiter one finds 3-4 reasonably compact retrograde families, corresponding to each of the previously known retrograde irregulars and one prograde family. ... That is contrary to the current doctrine that very little has happened to these irregular satellite families following their collisional formation. ...

spaceweb@oulu.fi - last update: 20 September 1998, 2020 UT (RR) . Traveling Convection Vortex (TCV) is a name given to a specific type of daytime magnetic impulsive events observed by high-latitude ground-based magnetometer arrays. Since the most likely source for TCVs is the solar wind , they are considered to be important processes in transfering energy from the solar wind into the magnetosphere . ... For example, one AMPTE Lithium release in the solar wind caused a TCV event . ...
