 ion: We derive equations of motion for the multi-orbital Anderson impurity
  model\, differentiating symmetrically with respect to all time arguments.
   The one- and two-particle Green's functions are thus related to correlat
 ors of up to six particles at four times. As an application we consider co
 ntinuous-time quantum Monte Carlo simulations in the hybridization expansi
 on\, which hitherto suffered from notoriously high noise levels at large M
 atsubara frequencies. Employing the derived symmetric improved estimators 
 overcomes this problem. .
