Second column denotes the analysis and datasets: current: experimentally identified; current_3X: experimentally identified in three or more experiments; Rcapture_HTP_vs_LTP: The Capture-Recapture analysis that used the HTP compendium and the LTP compendium (shown in bold as the most reliable estimate); Rcapture_1 %_noise: The Capture-Recapture analysis assuming 1 % noise in each dataset; CF_1 %_noise: The Curve-Fitting analysis assuming 1 % noise; CF_3X: The Curve-Fitting analysis based on the datasets that have been identified in three or more experiments. CF_best_start_1 %_noise: The Curve-Fitting analysis assuming 1 % noise and changing the order of the largest experiment as first; CF_best_end_1 %_noise: The Curve-Fitting analysis assuming 1 % noise and changing the order of the largest experiment as last; CF_half_exp_1 %_noise: The Curve-Fitting analysis assuming 1 % noise and using only the first half of experiments.
