tau's and sigma'sgreenspun.com : LUSENET : CU Statistical Orbit Determination : One Thread
Do we just try different values for each of the tau's in the DMC? Also for eq(28) in the DMC notes on the web, is sigma^2 a scalar? Do you have any suggestions as to what values to use?

Start with values for tau around 1e-7 and increase by a factor of 10 until it changes the results. Since you are doing RIC you need tauR, tauI, tauC, sigmaR, sigmaI and sigmaC. The handout I gave you is better than what is on the web. For those doing xyz, you really only need one tau and sigma.
