Statistical properties of the detected Sunrise Ca ii H BPs. a) Distribution of mean intensity contrast for all 5677 individual measurements (black, outlined histogram) and of the time averaged contrast of all 107 BPs (grey, filled histogram). b) Distribution of all 5570 individual measurements of horizontal velocity (black, outlined histogram) and of the values averaged over their respective lifetimes of the 107 studied BPs (grey, filled histogram). c) Histogram of mean size (diameter) of all 107 BPs (grey, filled histogram) and all 5677 individual measurements (black, outlined histogram). The vertical dashed line indicates the spatial resolution achieved by the Sunrise telescope. d) Histogram of lifetimes of 47 BPs (black, outlined histogram) and of corrected lifetimes (grey, filled histogram; see main text). The vertical solid lines indicates the mean values of the distributions. The fits (dot-dashed and dashed curves) are explained in the main text.
