Tomographic weak lensing cls with dn/dz #465

Open alexander-reeves opened 2 years ago

alexander-reeves commented 2 years ago

Dear all,

I am trying to get a theory prediction of the weak lensing cls for a specific survey with 5 tomographic redshift bins and hence 5 dn/dz distributions (one for each bin). I know it is possible to input a file specifying dn/dz for one bin in CLASS, and separately you can specify as many different redshift 'selections' as you want with a top-hat or Gaussian profile etc., but is there a way to specify 5 separate dn/dz files for the different bins? That would be extremely useful.

If it is not currently possible how difficult would it be to implement this?

Best wishes,

Alex

Were you able to implement this feature? It would also be very useful to me and I would rather not redo it my self if you have already looked at it although it does look fairly straightforward.
