Data set Examples¶
These plots show some of the data set loaders available in astroML, and some of the ways that astronomical data can be visualized and processed using open source python tools. The dataset loaders are in the submodule astroML.datasets, and start with the word fetch_.
The first time a dataset loader is called, it will attempt to download the dataset from the web and store it locally on disk. The default location is ~/astroML_data, but this location can be changed by specifying an alternative directory in the ASTROML_DATA environment variable. On subsequent calls, the cached version of the data is used.
For more examples, see the figures from the textbook.
