Atan merit function for tau1=45 and tau2 values of 1 (red), 5 (black) and 10 (blue) days.
And here is a plot of exponential weight evolution for taus of 5 (red), 10 (black) and 30 (blue) days.
This FOM is computed per field, per passband, for each potential observation. We can also introduce a couple of penalties:
