Documentation about the h5ad object missing

[Hannah-Doerpholz]

Thank you so much for providing comparable anndata objects. I was looking though one h5ad object. In anndata.var I stumbled upon the two columns "means" and "mean". Could you clarify what exactly these two columns refer to? I assume one of them refers to the mean expression of the gene across the dataset, but I don't know what the other column represents. The column "mean" also seems to have the column "std" associated to it, but I can't tell for sure what they refer to. Some clarification would be great!
