CRIME - Cosmological Realizations for Intensity Mapping Experiments CRIME is a set of computational tools that can be used to generate mock realizations of intensity mapping observations of the neutral hydrogen distribution. CRIME is made up of 3 separate tools: - GetHI: generates realizations of the temperature fluctuations due to the 21cm emission of neutral hydrogen. Optionally it can also generate a realization of the point-source continuum emission (for a given population) by sampling the same density distribution, although the use of this feature is discouraged for performance reasons (see the original paper for more details). - ForGet: generates realizations of the different galactic and extra-galactic foregrounds relevant for intensity mapping experiments. ForGet uses some external datasets (e.g. the Haslam 408 MHz map), which are stored in the folder "data". - JoinT: this is a convenience utility that joins the temperature maps generated by GetHI and ForGet and includes several instrument-dependent effects (in an overly simplistic way). The source code can be found in the folder "src/", and further details regarding the functionality of each of the programs is provided in the corresponding README files. Besides these, we also provide a set of convenience shell scripts that combine these 3 tools so that they can be run in one go. These are located in the folder "script". When in doubt, bear in mind that by default CRIME uses the following units: - Lenghts: Mpc/h - Frequency: MHz - Temperature: mK - Faraday depths: rad/m^2 License: CRIME (including GetHI, ForGet and JoinT) are distributed under the GPL license (see COPYING in the root directory). We kindly ask you to cite the program's website "http://intensitymapping.physics.ox.ac.uk/CRIME.html" and accompanying paper "arXiv:1405.1751" when using it for published results.

I was trying to run JoinT to combine the cosmological map and I ran into this error "Segmentation Fault (core dumped)" after Merging maps.
