"DU time stamp in B1, B0, B3, B2 order,
equivalent to the value 16,777,216*B3 + 65,536*B2 + 256*B1 + B0. The
value generates the SPACECRAFT_CLOCK count keywords in the label.
LOLA uses this value, together with a spacecraft time correction factor
that is uplinked from the ground and a clock correlation file to relate
this time stamp to terrestrial Atomic Time.

There are 6 phase A and 6 phase B Time-Digital-Converters.
Each TDC has a phase-locked-loop to control the gate delay time. A 1
in bits 0-5 indicates whether a corresponding phase A TDC has lost
PLL lock. Any bit = 1 indicates a fault.

Duty Cycle of the 12 TDC chips as counts, in B2, B1, B0 order,
subcommutated over 16 packets. This 24-bit value samples the TDC given by
the packet sequence number modulo 16, plus 1, for TDC numbers 1-12, while
13-16 are invalid. The 24-bit value is a signed integer. That is, if it reads
xFFFFFF, the actual value is -1. The full scale is plus or minus 199993 counts.
The maximum positive number is x030D39 (100% duty cycle); xFCF2C7 is the
full scale negative number (0% duty cycle).

Minor_Frame_Number
19
41
UnsignedByte
1
The number of the minor frame at which the
RX1_ENERGY to RX5_ENERGY values are sampled. The major frame for LOLA
is exactly 1 s, where time is defined by the 5 MHz clock provided by
the spacecraft. This particular analysis will consider the clock
to be true. Thus there are exactly 5x10^6 clock ticks per major frame.
LOLA has 28 shots per second, where each shot is defined as a minor
frame. This gives 178571.42857... clock cycles per minor frame.
The LOLA minor frames will not be exactly equal in length but will be
fully deterministic, using an old digital phase lock loop technique
designed for SMEX/FAST many moons ago.
The first 16 minor frames will be 178571 clock ticks in length.
The last 12 minor frames will be 178572 clock ticks in length.

LOLA Science Data for each laser shot minor frame.
The science data consist of time stamps relative to the shot
reference time (T0) of various triggers. The times are recorded
on both the leading and trailing edges of each trigger to determine
the centroid of the detected pulse. There are flags associated with
each channel of the range measurement unit (RMU) that indicate
whether the RMU counts are valid, followed by status and phase
indicators for the time-digital converters (TDC) to be used in
calibrating the time stamps. Each time stamp is composed of column
definitions for four separate event counts produced by the RMU.
The four events are:
a coarse (200 ns) event count;
event 1, a fine counter for leading edge.
event 2, a fine counter for trailing edge;
event 3, a fine counter for leading and trailing edges.
Each pulse time stamp is calculated in nanoseconds from T0 as
le = 200.*coarse -(event1 - event3)*0.02815
te = 200.*coarse -(event2 - event3)*0.02815
pw = (event1 - event2)*0.02815
Each counter is coded in three bytes (B2, B1, B0), starting with
the most significant byte, for a total of 12 bytes/stamp.
The fine counter least significant bit is approximately 28.15 ps.
There are seven time stamps for each shot: a transmit time TX,
five lunar receive times RX1-5, and one Earth window time.
The earth window is gated separately on Channel 1 and precedes the
lunar gated pulses, but shares a common timing format.
The column definitions for time stamps are followed by a software
timer, and digital counts of the lunar RX1-5 energies.
