Data are merged together, upon export from both systems, as FITS files. The image data are stored separately on disk, and managed by the Storage Unit Management System (SUMS). The metadata are stored in a SQL database, which is handled by the Data Record Management System (DRMS). In addition there is an IPython notebook that shows how to use the drms module to plot, query, visualize, and export the data in a variety of formats.ĭata from the HMI and AIA instruments are stored at Stanford University. The drms manual is available on the Read the Docs website, and contains a detailed tutorial. The drms module can be installed from PyPI and its source code is available on Github, where also many example scripts are included in the examples subdirectory. It allows the user to query metadata independently of image data, export tailored FITS files and serve these files in a variety of methods, and export data as movies and images in different formats. Of the Python-based methods to access solar data, the drms module has some unique capabilities.
We have released a new Python module, called drms, to access the HMI and AIA data provided by the Joint Science Operations Center (JSOC). Two of the most popular methods, aside from a direct web interface, use the SolarSoft library in IDL and the SunPy library in Python. There are many different ways to obtain data from the Solar Dynamics Observatory’s (SDO) Helioseismic and Magnetic Imager (HMI) and Atmospheric Imaging Assembly (AIA) instruments.
