SOHO Telemetry Subformat Definitions — Feb 10,11 1997 to Sept 25,26 1997

February 10,11 1997: Submodes 5 and 6 were added, respectively.

Submode 5 was added into the programmable submode. Submode 5 added 12 extra packets to LASCO/EIT (24 —> 36 packets) and became the new "nominal" operating submode replacing Submode 1. Submode 1 was patched to give all SUMER science telemetry to LASCO/EIT and renamed as Submode 6.

Number of Packets Acquired Per APID in Each Subformat

APID Packet Size (in bytes) Submode 2 (LASCO/EIT high) Submode 3 (CDS high) Submode 4 (SUMER high) Submode 5 (NOMINAL) Submode 6 (LASCO/EIT extra)
