The uncertainty in the 3161800100024 absolute efficiency curve at 2.8cm was estimated to be 3161800100025 approx. 2%, and the uncertainty of the activity of the 3161800100026 standard source was approx. 1%. 3161800100027 METHOD (ACTIV,GSPEC) 3161800100028 MONITOR (41-NB-93(N,2N)41-NB-92-M,,SIG) 3161800100029 DECAY-MON (41-NB-92-M,10.15D,DG,934.44,0.9907) 3161800100030 MONIT-REF
