Here is a graph showing the weekly values of Opportunity's Watt Hours, Tau, and Dust Factor (as stated in the weekly Opportunity Updates on the main Mars Rover website) from January 2010 to July 15, 2010.
Low tau's are good -- high dust factors are good. A tau of 4.7 is a 99% blocked atmosphere - we are in a very clear sky period ( t=0.2) I am assuming a dust factor of 1.0 is how Oppy left the clean-room. Notice when Tau goes up (sol 2253) and the Dust Factor goes down, the power goes down. And when tau is very low (sol 2300) and the dust has been cleaned off (0.7) the power zooms (for what is available in winter!). The winter solstice was Sol 2260 ( i think?) For a review of Tau, I refer you to Emily's awesome recap of the (click) 2007 Dust Storm I haven't found a good description of the dust factor yet(!) Cheers -------------------- CLA CLL
