LATEST VERSION UPDATE: 21 november 2000 DOWNLOAD Aberratorv252.zip Due to problems using the zoom in the Double-pages I have disabled zooming in that page (other pages unaffected). A new V2.53 is available in the AberratorV2.52 file !. The bugs in V2.5 are resolved, V2.52 was a complete update with only a few new features (coloured wavefront image). IMPORTANT NOTE :Please DO install all the files in one directory !!

General information: Version 2.5 looks very much alike the V2.4 beta, but inside several important changes have taken place. For more information about V2.4 look at Previous release and for the latest development information look at the News page. Important changes: Startest images: The previous versions have shown light intensity scaled as a square-root function, the new intensities are depicted using a gamma/slope function. Planetary Images(saturation): All previous version from the Aberrator suffered from saturation in the planetary images. From V2.5 this problem has been solved. Double Stars: The brightness of the two stars at close range is simulated more realistic than in the V2.4. Also you can now set the separation to the DAWES and RAYLEIGH criteria directly.
PSF/MTF: The PSF shows arcseconds on the X-axis. Also the PSF-values on the Y-axis are properly scaled. The peak values (at focus=0) can now be compared to strehl-ration (for unobstructed telescopes).
Wavefront : The values of the Peak-Valley (PV) and the RMS (Root Mean Square) of the current set of aberrations are shown both as numerical and reciprocal values (eg. 0.1 and 1/10 wavelength error). About:On the about page a special white->black shade image was added. Tune your screen’s contrast/brightness settings so that you can see all the shades. |
