SOHO Telemetry Subformat Definitions

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.
