tutorials\n===================\n\nNotebooks on how to use [`mapsims`](https://github.com/simonsobs/mapsims) and [Simons Observatory's map based simulations](https://github.com/simonsobs/map_based_simulations).\n\nFor any errors or feedback, open an issue on this repository.\n\n## Recording of the 1-hour tutorial (June 2020)\n\n[![Youtube video](https://img.youtube.com/vi/kzERT42qyZs/0.jpg)](https://www.youtube.com/watch?v=kzERT42qyZs\u0026start=148)\n\nOr download the video in MP4 format from the [Simons Observatory wiki (needs credentials)](http://simonsobservatory.wikidot.com/ff2f-recordings)\n\n## Review notebooks without executing them\n\nSee the [already executed notebooks](https://nbviewer.jupyter.org/github/zonca/mapsims_tutorials/tree/executed/)\n\n## Setup at NERSC\n\n* Login to [Jupyter@NERSC](https://jupyter.nersc.gov)\n* Open a terminal\n* Clone this repository:\n\n        git clone https://github.com/simonsobs/mapsims_tutorials\n\n* Run the kernel installation script:\n\n        bash install_mbs_kernel_nersc.sh\n\n* Refresh the browser page\n* You should have now the \"Simons Obs MBS\" kernel\n\n\n## Local setup\n\nThe only tricky dependencies of `mapsims` are `healpy` and `pysm3`.\nIt is easier to install them with Conda, but pip should work as well:\n\n        conda create -c conda-forge -n mbs python=3.7 astropy healpy pysm3 numba h5py libsharp=*=*openmpi* mpi4py ipykernel\n\nThe tutorial requires `mapsims`, `so_noise_models` and `pixell`, they can be installed with:\n\n    pip install -r requirements.txt\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsimonsobs%2Fmapsims_tutorials","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsimonsobs%2Fmapsims_tutorials","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsimonsobs%2Fmapsims_tutorials/lists"}
