(a) Calculated uncertainties (values in parentheses) reflect twice the standard parameter fit error. The DJ, DJK, and DK parameters for 
were constrained to the calculated υ+ = 0 values. (b)Errors on parameters (values in parentheses) are equal to once the standard deviation. (c)A positive value of the ℓ-doubling parameter q here means that the 
component of the J = |k| = 1 level, which has zero spin-weight, is lower in energy than the 
component.
