... This discussion begins by noting that stellar photometry is often done quite effectively on unrestored images. Even when restoration is necessary, one must be wary of sophisticated methods, many of which distort photometric values. ... A completely unsolved problem is presented: estimating the arithmetic difference between two images that have different PSFs and different . ... I think that Bob really did want you to hear from some people who represent the user community of image restoration. ...

In this talk we will present a series of results and open problems emerging from the study of infinite global fields. We will give a survey of the asymptotic properties of the Brauer-Siegel and Euler-Kronecker invariants in the classical situation of number fields and function fields as well as in certain higher dimensional cases. ...

... Forum: The Linux Kernel Hackers' Guide . ... For mounting the files I used the following command in Linux: mount -t msdos /dev/fd0 /mnt But after the mounting in /mnt I had different garbled file names such as rtlinu~1 & kernel~1. ... But the problem is how? ... Which command should I use? ... Another problem was, I tried to patch those files to the kernel and it started asking me the question : File patch to, which files should i mention, or is it another problem because of the original problem? ...

Next: Initial conditions Up: Old neutron star distribution Previous: Introduction . The problem to be solved is to find stationary space distribution of stars which have had certain initial space and velocity distributions and move in a given potential. ... In principle, the most straightforward way to obtain the solution is to integrate directly the equations of motion for a sufficiently large number of stars with different initial conditions. ... Then space density is given by . ...
