Plots of Chi square / degree of freedom analysis of a fit of a constant to the gain vs run for each tube.

• page 1
• top: old method
• bottom: new RSMON correction applied
• page 2
• log plot of an overlay of the two page 1 plots
• page 3
• top: ratio of old / new
• tubes that worsen from old to new have values <1
• there are 24 - 35 with bad values  (however only 6 are bad worsen significantly)
• bottom: difference of old - new
