Table 6 Sensitivity of the KfiA to basic parameters for an 1896 X-ray tube with glowing anode

Rosenfeld (1897) [59]	T_anode	ε	t_exposure	Wall	FSD	KfiA	Total change KfiA towards
Rosenfeld (1897) [59]	°C	ε	min	mm	cm	mGy	lower values	higher values
Parameter value	750	0.69	50	0.60	39	334
Variation considered^a	100^a	0.14	5	0.15	3		51%	67%

^aThe change of 100 °C in T_anode could be a realistic uncertainty (say standardard deviation), but we simply do not know due to lacking information. The other uncertainties in basic parameters are deemed realistic
