... HST . ... HST Overview . ... Retrieving HST Data . ... The shape of the spectrum and its overall level are closely tied, which is why both sensitivity and vignetting were discussed in the previous section. ... Thermal drifts caused a spectrum to move on the photocathode, so the GHRS routinely performed a SPYBAL (spectrum Y-balance) to properly center the spectrum on the diode array. ... In some cases the shape of a spectrum can be distorted if the background is improperly calculated and subtracted. ...

... Forum: The Linux Kernel Hackers' Guide . ...

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? ...

A problem, that can arise when moving from Fortran 77 to Fortran 90, is dependent on a usual deviation from the standard, and has to do especially with user programs. ... With many Fortran 77 implementations we wrote PROGRAM TEST REAL X WRITE(*,10) 10 FORMAT('Give X = ',$) READ(*,*) X WRITE(*,*) X END In Fortran 90 we use "non-advancing I/O" instead. ... In some old Fortran dialects the statement TYPE was used to write on a typewriter terminal and PRINT was used to write on the line printer. ...

... The planning and reduction programs are distributed with array sizes set large enough to let most observers work without difficulty. However, you might need to reduce a very large data set, or to deal with a very large number of passbands (9 is the nominal limit). ... The main problem is holding the matrix of normal equations during the iterations; on the other hand, star catalogs can be made quite large without paying much of a price in terms of performance. ...

Russian SHAREABLE DATA CENTER Institute of Solar-Terrestial Physics SB RAS . ... A most promising problem is to investigate the interaction of two VHF powerful radiowave beams in the ionosphere, whose difference frequency is equal to the plasma frequency in some ionospheric area (that is, the difference frequency is taken in the range 1-8 MHz). ... Two-frequency interaction effects are based on radiowave non-linear mixing, which is rather complicated when describing and modelling the experiment. ...
