PyGSM | Python implementation of the Global Sky Model

PyGSM is a Python library. PyGSM has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

PyGSM is a Python interface for the Global Sky Model (GSM2008) of [Oliveira-Costa et. al., (2008)] and recently [Zheng et. al., (2016)] GSM2016. The GSMs are all-sky maps in Healpix format of diffuse Galactic radio emission from 10 MHz to 94 GHz (GSM2008) and 10 MHz to 5 THz (GSM2016). This is not a wrapper of the original code, it is a python-based equivalent that provides a useful API which has some additional features and advantages, such as healpy integration for imaging. The GSM2008 and GSM2016 classes provided here are designed to have the same API (i.e. function names & usage). Instead of the original ASCII DAT files that contain the principal component analysis (PCA), from the GSM2008, data are stored in HDF5, which can be quickly read into memory, and takes up less space to boot. Similarly, the GSM2016 data is converted into HDF5.
