I am working on astrophysical data and I have a large number of redshift values of quasars. Now, each redshift estimate comes with its estimated standard error naturally. If I plot a histogram of these redshifts, I would expect the bins counts to also have some sort of uncertainty. I am unable to figure out how the uncertainties in the redshift estimates propagate to the bin counts. I also seem to be unable to phrase this properly and get material online that addresses this problem. Any suggestions as to how to go about computing the uncertainties? It would also be a great help if I could get some references.
