On the mass distribution of the LIGO-Virgo-KAGRA events

We present here the data we extracted from the black wholes with primary and secondary masses  > 4 M⊙ in the GWTC-3 catalogue. We obtained this data by associating a skewed normal distribution to the primary mass and secondary mass of each event, that we then used to construct the mass ratio probability density function for each event. We then stack and discretise those pdfs to construct histograms of primary mass and mass ratio distribution. (see https://arxiv.org/abs/2409.00179 for a detailed description)

A text file and numpy array version of bincount files are provided. Each entry in the array is the number of couts per bin in the bin that corresponds to the index of the entry. We use 15 bins in logspace between 3 M⊙ and 110 M⊙ for the primary mass histogram and 10 bins between 0 and 1 in linear space for the mass ratio histogram. 

The error files (text and numpy array versions) include the Poisson errors (upper, lower and average) on the number of counts in each bin. Please see arXiv:2409.00179 for more details.
