0005  *  DB object for storing per-SL DT reconstruction parameters (ttrig, vdrift, uncertainties),
0006  *  possibly with their dependency from external quantities (like position, angle, etc.)
0007  *
0008  *  Dependencies can be specified  with the expression set by setFormula(string), representing:
0009  *  -a TFormula,  e.g. "[0]+[1]*x", in the most general case;
0010  *  -special cases like "[0]" = fixed constant, that are implemented without calling TFormula.
