Detail Files

Detail files store spatial quantities, such as eigenfunctions and differential inertias, for an individual solution (mode, tidal response, etc.) found during a run. The specific data written to detail files are controlled by the detail_item_list parameters of the &ad_output and &nad_output namelist groups (gyre adiabatic and non-adiabatic calculations, respectively) and the &tides_output namelist group (gyre_tides calculations). These parameters specify the items to be written, via a comma-separated list.

The following subsections describe the items that may appear in detail_item_list, grouped together by functional area. For each item, the corresponding math symbol is given (if there is one), together with the datatype, and a brief description. Units (where applicable) are indicated in brackets [].
