I have this mars image, and I want to know exact sunlight direction in degrees, but I'm quite confused by data available in this file: http://www.planetmobile.it/jumpjack/buchi-marte-dati-completi.txt (Fields list) (original file WARNING!! 50 MB!!) If local time is past 12 PM, how can the solar longitude be minor than image longitude?!? Please Register or Log in to view the hidden image! (original image)
