Orbit number is a unique identifier for a
given orbit of the MESSENGER spacecraft around Mercury.
Orbit number is defined as starting at apoherm and is
calculated using the MET value and the appropriate SPICE
kernels. Orbit numbering does not start until MESSENGER
performs the Mercury orbit insertion. Until that time the
value for orbit number is 0.

UnsignedByte
1
Solar flare handling enacted flag. Allows software
to determine if solar flare handling has already been enacted or
whether this is a new detection of a solar flare. Only checked if
solar flare handling has been enabled (see previous field).
=0 the software sets it to true, starts the sf-time-enactable-left
counter out at sf-max-time-enactable, sets a flag telling the 1Hz
process to end the current integration and reporting period
immediately, and returns control to the 1Hz process. =1 , the
software decrements the sf-time-enactable-left counter and checks
its value. If sf-time-enactable-left is still greater than 0, the
algorithm does nothing further. If sf-time-enactable-left has reached
0, the algorithm starts the sf-timeout-left counter out at
sf-timeout-period and sets the sf-handling-enacted-now flag to false.

A 10 element array of solar monitor detector rate
measurements. The integration period is divided into 10 equal
segments with an accumulated rate (per second) for each. Valid
data for this column is only obtained by the instrument if solar
flare handling is enabled at the start of the integration and
reporting period. Values are set to a default of 999 if solar
flare handling was not enabled.
