This table contains X-ray spectra and associated instrument
parameters, as observed by the MESSENGER X-Ray Spectrometer (XRS).
Detailed descriptions for the parameters defined below are contained
in the EDR SIS document.
An XRS flight software upload was implemented on 2007-08-17 UTC
that affects COLUMN 40 of the XRS raw binary table. Prior to 2007-08-17,
column 40 was named LVPS_SPARE2 and was a spare, unused data column. On
and after 2007-08-17 the column is used to indicate the SAX_TEMP_MODE.

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.

=0 level zero or nominal level safing; the software will monitor the
planetary detector for the conditions that necessitate a higher
level of safing.
=1 level 1 safing; the HVPS voltage level for the affected sensor is
ramped down to 0 at a rate of 100 V/sec.
=2 level 2 safing; the software turns off analog power to the
affected sensor and turns off the associated HVPS. No further
attempts are made to restore the level-two-safed sensor to nominal
safing. The software waits for ground command to reset the affected
HVPS voltage levels.

detector.

level of safing.
=1 level 1 safing; the HVPS voltage level for the affected sensor is
ramped down to 0 at a rate of 100 V/sec.
=2 level 2 safing; the software turns off analog power to the
affected sensor and turns off the associated HVPS. No further
attempts are made to restore the level-two-safed sensor to nominal
safing. The software waits for ground command to reset the affected
HVPS voltage levels.

detection (see SOLAR_FLARE_ENACT).
flare_handling_enacted
32
45
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.

2
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.
solar_monitor_spect_shift

UnsignedMSB2
2
The divisor (bit shift) for the Solar Monitor
spectrum. When any channel in the solar monitor spectrum exceeds
65535, the spectrum is shifted to the right, throwing out the least
significant bits, keeping the 16 most significant bits.
