... A frequently used procedure, alternative to the correction for the chromatic response, is to normalise the continuum to unity by dividing the observed spectrum by a smooth approximation of its continuum. This approximation can be obtained either interactively with the graphic cursor, or from a table (command NORMALIZE/SPECTRUM ) or by dividing the raw data by itself after filtering or smoothing. Median filtering and running average algorithms are well suited for this purpose (command FILTER ). ...

Can I use Tiny Tim models in programs like DAOPHOT? This is actually the most frequently asked question. ... Some filters are not included since they are "weird" or cover a range of separate wavelengths, like the linear ramps. ... When Tiny Tim asks for the filter name, just enter "none" or "mono". ... How can I adjust the focus of the Tiny Tim models? ... Can Tiny Tim model the NICMOS coronographic mode? ... What's the deal with the pixel scattering function in WFPC2? ...

... We consider stars with a constant (solar) initial chemical composition. Before the Roche lobe overflow, the components evolve as single stars (see for details LPP96). ... If the mass transfer onto a normal star occurs on a time-scale ten time shorter than the thermal Kelvin-Helmholz time for this star or a compact star is engulfed by a giant companion (e.g. as a result of the kick), the common envelope (CE) stage of the binary evolution is set in (Paczynski 1976). ...

It is the relatively weak distortions of the many distant faint blue galaxies all over the image, however, that indicates the existence of the dark matter ring. ... A hypothesis for the formation of the huge dark matter ring holds that it is a transient feature formed when galaxy cluster CL0024+17 collided with another cluster of galaxies about one billion years ago, leaving a ring similar to when a rock is thrown in a pond. ...
