The SKYSAMPLER survey emulator¶
skysampler is a python package which can draw random realizations of survey data, with the special aim of creating random realizations of galaxy clusters and their surrounding galaxies.
- Handles wide field survey data to learn the joint feature distribution of detections and galaxies
- Draws mock realizations of cluster line-of-sights
- Provides interface for GalSim to render the mock catalogs into full survey-like exposures
Generating mock observations takes place in a data driven way, i.e. clusters are constructed as they are seen in the survey, not according to our theoretical models for them, hence the products are not critically dependent on our physical assumptions, only on survey conditions.
