RFC : accesses to data

[johannct]

Currently, CLMM does not have any "reader", be it a class, a module, or a package, that abstracts access to the needed input to CLMM :

• cluster finder algorithm
• galaxy catalog
• photoz-catalog My understanding is that CLMM needs a list of clusters, and for each clusters a list of cluster members and a list of background galaxies. Is CLMM in charge of building this set of background galaxies from the galaxy catalog, or is it provided by an external software? Then CLMM will need, or not, the pdfs for all galaxies of interest in the GalaxyCluster object, members and sources I presume. All this should be clarified in the CLMM API, irrespective of the concrete implementation that will actually access data products
