"Pseudo-MPEC" for Unkno1
Created Thu Jan 19 14:31:56 2012 using Find_Orb
Based on data from the TAROT scope (click here for details) and data from (844) Los Molinos kindly provided by Gonzalo Tancredi. The two (844) points fit in well enough to confirm what's going on, though the residuals were a little too high to be included in the orbital fit.
TAROT also tracked a second object; click here for a pseudo-MPEC for the other object.
