Summary Files¶

A summary file gathers together information about all modes found during a GYRE run. The data written to summary files is controlled by the summary_item_list parameter of the &ad_output namelist group (for adiabatic calculations) and the &nad_output namelist group (for nonadiabatic calculations). This parameter is a comma-separated list of items to appear in the summary file. The items come in two flavors:

• scalar items comprise a single value, typically pertaining to all modes (i.e., a global quantity)
• array items comprise a sequence of values, with each value pertaining to a single mode. The sequence follows the same order in which modes were found during the GYRE run.

The following subsections describe the items that may appear in a summary_item_list parameter, grouped together by functional area.
