Detail Files

A detail file gathers together information about a single mode found during a GYRE run. The data written to a detail file is controlled by the detail_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 detail files. The items come in two flavors:

  • scalar items comprise a single value, typically pertaining either to the star as a whole (i.e., a global quantity) or to a specific location in the star
  • array items comprise a sequence of values, with each value pertaining to a single point in the discrete grid used to solve the oscillation equations. The sequence runs from the inner boundary to the outer boundary

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