Simulated mean number of clusters as a function of pileup for Disk 1 Ring 1 of the Tracker Endcap Pixel Detector (TEPX). The figure shows the linear behaviour of the mean number of clusters over the full pileup range from 0 to 200. The data points are fitted with a firstorder polynomial in the pileup interval from 0 to 2, and the extrapolation to pileup 200 is shown with a 95% confidence interval. This is done to replicate the principal approach taken with the van der Meer calibration.

Simulated mean number of clusters as a function of pileup for Disk 4 Ring 1 of the Tracker Endcap Pixel Detector (TEPX). The figure shows the linear behaviour of the mean number of clusters over the full pileup range from 0 to 200.

Relative nonlinearity for each disk of the Tracker Endcap Pixel Detector (TEPX). The deviation is calculated as the relative difference between the data point and the value of the fit function at the respective pileup value. For each disk, the size of the box is determined by taking the minimum and maximum deviations across all rings. For clusters, this deviation is smaller than 1% over a pileup range from 0 to 200. 

Simulated mean data rates per module for each ring of all Tracker Endcap Pixel Detector (TEPX) disks at pileup 200 and a rate of 75 kHz of zerobias triggers. The mean rates are shown with their standard deviation, accounting only for the RD53B specific encoding and do not include overhead of any link layer protocol.
