Some of the\ninformation provided is approximate, aimed towards fast simulations rather than full accuracy in\nrepresentation of Euclid images.  Places where the information is only approximate are flagged and\ndescribed in the docstring, and we particularly highlight that the PSF is only approximate;\nfor details, see the docstring of the ``getPSF()`` method.  This library should enable generation of\nEuclid-like images of sufficient fidelity for preliminary exploration of object detection,\nphotometry, deblending, and joint analysis with ground-based observatories.  For\napplications requiring high precision such as weak lensing, the higher fidelity simulations\navailable within the Euclid Consortium should be used.\n\nThis repository includes two distinct packages:\n\n* ``euclidlike``: has basic observatory, instrumentation, and survey information for Euclid.\n  This package can be used on its own along with GalSim to produce Euclid-like simulations.\n\n* ``euclidlike_imsim``: has configuration scripts to produce large-scale Euclid-like simulation runs\n  based on the information in ``euclidlike``. It is based heavily on `roman_imsim \u003chttps://github.com/matroxel/roman_imsim\u003e`_.\n\n\nReferences\n==========\n\nFor more information about `GalSim \u003chttps://github.com/GalSim-developers/GalSim\u003e`_, please see its README and documentation.\n\nFor more information about Euclid, please see the `Euclid Consortium website \u003chttps://www.euclid-ec.org/\u003e`_ and papers linked from there.\n\nAttribution for software and data used by particular routines in this library is given in the docstring for the relevant routine.\n\nInstallation\n============\n\nThe source code for GalSim-Euclid-Like has not been published to pypi. To install from source code::\n\n    git clone git@github.com:GalSim-developers/GalSim-Euclid-Like.git\n\nand install by running::\n\n    conda create -n euclidlike python=3.10\n    cd GalSim-Euclid-Like\n    conda activate euclidlike\n    pip install .\n\nPlease view the `Installation Instructions` (in INSTALL.rst) for further details on how to install GalSim-Euclid-Like.\n\nDownloading relevant data\n=========================\nThe Euclid-like PSF is constructed from precomputed oversampled images on a grid in focal plane position and wavelength. To use the full FOV PSF within GalSim-Euclid-Like, the images must be downloaded by running::\n\n    $ euclidlike_download_psf\n\nin the terminal after installation of GalSim-Euclid-Like. To install in an alternative directory to the default, use the ``--dir`` argument. Refer to the ``getPSF`` documentation for further details about the PSF. \n\nGetting started\n===============\n\nPlease see the examples/ directory for demos illustrating the use of this code.\n\nCommunicating with the developers\n=================================\nFeel free to `open a GitHub issue \u003chttps://github.com/GalSim-developers/GalSim-Euclid-Like/issues\u003e`_ to reach the developers with questions, comments, and bug reports.  New contributors are also welcome and can indicate their interest in developing this code base through the Issues.\n\nAttribution\n===========\n\nThis software is open source and may be used according to the terms of its `license \u003chttps://github.com/GalSim-developers/GalSim-Euclid-Like/blob/main/LICENSE\u003e`_.\n\nWhen using this software, please provide the URL to the repository in the resulting paper or note.  Once there is a Zenodo DOI or journal article, this README will be updated and we will ask those using the code in their research to cite the relevant journal article.\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgalsim-developers%2Fgalsim-euclid-like","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgalsim-developers%2Fgalsim-euclid-like","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgalsim-developers%2Fgalsim-euclid-like/lists"}
