description During my summer project I calculated the rates of the MonB counters from the VeloPix ASICs. Using these rates, I then studied the luminosity of the collisions in the LHCb detector. Studying archiving of the MonB data from past runs we realized that the rates and luminosity have a linear relation and the linear fit parameters can be used to calculate luminosity in real time. Secondly, the VELO team has a goal of setting up all of the ASIC DAC thresholds so that the noise rates are all close to a goal rate. I developed an algorithm to set these thresholds automatically in a single scan.
