However, this is better handled with the new catch multiplier option.

 Indices are data that are compared to aggregate quantities in the model. Typically, the index is a measure of selected fish abundance, but this data section also allows for the index to be related to a fishing fleet's $F$, or to another quantity estimated by the model. The first section of the ``Indices'' setup contains the fleet number, units, error distribution, and whether additional output (\gls{sd} Report) will be written to the Report file for each fleet that has index data.
