 ##### Aggregation selection
 
-A validator is selected to aggregate based on the computation in `is_sync_committee_aggregator` where `state` is a `BeaconState` as supplied to `get_sync_committee_selection_proof` and `signature` is the BLS signature returned by `get_sync_committee_selection_proof`. 
+A validator is selected to aggregate based on the computation in `is_sync_committee_aggregator` where `signature` is the BLS signature returned by `get_sync_committee_selection_proof`. 
 The signature function takes a `BeaconState` with the relevant sync committees for the queried `slot` (i.e. `state.slot` is within the span covered by the current or next sync committee period), the `subcommittee_index` equal to the `subnet_id`, and the `privkey` is the BLS private key associated with the validator.
