  • Oh, I understood now. They have a greyscale image (the original) and then they project that on a map. I think that explains why the trails also have the texture of the terrain although they are supposed to be trails of a dust devil. The white band is also there but is not so anoying in the greyscale image. Hopefully NASA knows their business.

  • Conditional support if someone can translate "Latitude (centered): 26.7 °. Longitude (East): 62.8 °. Range to target site: 284.9 km. Original image scale range: 57.0 cm/pixel (with 2 x 2 binning) so objects ~171 cm across are resolved. Map projected scale: 50 cm/pixel and north is up. Map projection: EQUIRECTANGULAR. Emission angle: 0.3 °. Phase angle: 51.3 °. Solar incidence angle: 51 °, with the Sun about 39 ° above the horizon. Solar longitude: 326.8 °, Northern Winter." into some appropriate language in the caption that explains the size of the area depicted in this photograph and of the features shown in it. Translating Martian longitude-latitude coordinates into kilometers is left as an exercise for the reader. Spikebrennan (talk) 16:17, 30 November 2009 (UTC)[reply]
