HSB Packet Counts: This type tracks counts of packets received during an interval by conditions under which they were received
| Field Name | Type | Explanation |
| missing_in | 16-bit integer | Count of packets missing between packets that are present |
| missing_ends | 16-bit integer | Count of packets missing at beginning or end of granule timespan: missing packets for which there are either no existing packets before them or no existing packets after them. (When all data is missing all packets will be counted here) |
