GSM File Format
Files in GSM (GYRE Stellar Model) format store HDF5 data describing a
stellar model. This format is intended as a portable,
storage-efficient alternative to the MESA File Format. To
create one of these files in MESA (from revision 21.12.1 onward), set
the pulse_data_format
parameter of the &controls
namelist group to the value 'GSM'
.
The GSM format adheres to the following conventions:
All data objects are attached to the root HDF5 group (/)
Real values are written with type H5T_IEEE_F64LE when GYRE is compiled in double precision (the default), and type H5T_IEEE_F32LE otherwise
Integer values are written with type H5T_STD_I32LE
There are a number of versions of the GSM format, distinguished by the
version
attribute in the root HDF5 group:
