If there is a sun in the description, gendaymtx\nwill include its contribution in the four nearest sky patches, distributing energy\naccording to centroid proximity.\n```\n\nThis means that the direct sun is diffused between several sky patches and so the\nprecise line between shadow and sun for each hour is blurred. This approximation\nis fine for studies where the timestep-by-timestep irradiance values do not need\nto be exact. For accurate modeling of direct irradiance on a timestep-by-timestep\nbasis, see the `annual_irradiance` recipe.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpollination%2Fcumulative-radiation","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpollination%2Fcumulative-radiation","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpollination%2Fcumulative-radiation/lists"}
