\section*{GYRE Stellar Model (GSM) Format}

GSM-format files store data describing a stellar model in an
HDF5-format file. The attributes of the root group contain global
stellar parameters, while 1-D datasets contained within the root group
specify the structure data on a grid of $n$ points extending from
center to surface. These attributes and datasets are defined as
follows:
