Cosmology distance

[christianboily]

Hi, Just a comment -

When I installed the cosmolopy module with pip3 (python 3.9) I then tried to use the TreeGen package - but I am missing a module called fast_histogram which does not appear to be listed as a pip-dependency in your installation instructions : same for lmfit. It might be useful to state this explicitly (could be a local module e.g.).

If I missed the instructions please ignore this message.

I did find the cosmopy package etc and found that there will be major changes with the utils module starting with py3.12 : presumably this will impact SatGen, too.

best wishes, chris b.
