It is part of the [RvSpectML family](https://rvspectml.github.io/RvSpectML-Overview/) of Julia packages.  \nExamples of using it with other RvSpectML packages can be found in the examples and/or notebooks folders of the [RvSpectML](https://github.com/eford/RvSpectML.jl) and [RvSpectMLPlots](https://github.com/RvSpectML/RvSpectMLPlots.jl) packages.  \n\n## Examples\nThe EchelleCCFs package includes a few simplistic tests and one example of applying it to simulated solar spectra from [Gilbertson, Ford \u0026 Dumusque 2020](https://doi.org/10.5281/zenodo.3753253) which is described in the associated [Research Note of the AAS](https://ui.adsabs.harvard.edu/link_gateway/2020RNAAS...4...59G/doi:10.3847/2515-5172/ab8d44).  \nThe input file for this example is large, so it is not part of the GitHub repository, but is downloaded as part of the build process for the the package.\nTo install the package, download the simulated data and perform a CCF calculation, you can run\n\n```julia\nimport Pkg\nPkg.add(\"EchelleCCFs\")  # Installs EchelleCCFs and required dependancies\nusing EchelleCCFs       # Loads EchelleCCFs\ncd(joinpath(pkgdir(EchelleCCFs),\"examples\"))  # Change into examples folder\nPkg.activate(\".\")      # Specify to use Project.toml in examples folder\nPkg.instantiate()      # Installs extra packages for example\ninclude(\"soap_ccf.jl\") # Run example CCF calculation and make plots\n```\n\nTo analyze more spectra from the [Gilbertson, Ford \u0026 Dumusque 2020 dataset](https://doi.org/10.5281/zenodo.3753253), you'll need to download even larger file(s), as illustrated in `deps/download_soap_example_from_gilbertson_etal_2020.jl`.\n\nGood luck.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frvspectml%2Fechelleccfs.jl","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Frvspectml%2Fechelleccfs.jl","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Frvspectml%2Fechelleccfs.jl/lists"}
