Summary
[edit]Description5000 Years of Total Solar Eclipses (SVS5222 - eclipse freq float).tiff |
English: A grayscale version of the heatmap showing the frequency of total solar eclipses over the 5000 years from 2000 BCE to 3000 CE. The floating-point image contains the actual count of eclipse paths crossing each pixel. Fractional counts indicate the edge of a path passed through only part of the pixel. The 8-bit image stretches the count over the full 0 to 255 range of pixel levels. Divide each pixel level by 34.216 to match the floating-point levels. |
