Dataset for Intergenerational scaling law determines the precision kinematics of stochastic individual-cell-size homeostasis

### Data Source

Taheri-Araghi et al., 2015 [^1]

### Changes

- The conversion factor to convert the length values (reported in pixels in the data source) to μm was changed from the value 0.065 μm/px reported in the data source, to 0.0645 μm/px, to better match the actual length values in μm presented in [^1].- The initial length values recorded in the data source have a constant negative offset of 1 pixel length from the corresponding length values from the full time series recorded in the data source, thus, the length values in the full time series were reduced by 1 pixel length to match the initial length values.- To avoid noise in the measurement of initial lengths and the discretness in recorded values due to a least count of 1 pixel length, the initial length values were recalculated by fitting each generation's time series of the log of length to a linear curve, assuming length increases exponentially between cell divisions.- The exponential growth rates reported in the data source had been obtained from the slope of a linear fit of the time series of the log base 2 of cell lengths (which have a 1 pixel length offset from the corresponding reported initial lengths). These growth rates were recalculated using the same procedure, except with the natural log instead of log base 2, and after subtracting 1 pixel length from the recorded cell lengths to account for the discrepancy from the recorded initial lengths.

### Steady State

Of the full dataset, the values used in our manuscript [^2] are taken from the steady state portion, which was obtained by filtering out the initial and final parts of the time series where the average division time and growth rate values (averaged over all cells) vary over time.
