MROM_0226:

Images B03_010688_1533_MA_00N121W.IMG through
B03_010721_1546_MA_00N302W.IMG were affected by what was likely
a single-event upset in the MARCI DSP changing a value in the
companding table; bright (dn=174) pixels are scattered throughout
those images.  MARCI was commanded to reboot at 11/8/2008
22:17:17 SCET UT in order to reload the companding table.

MROM_0076:

MARCI was powered off at approximately 13:52 on 2007-07-20, during
acquisition of frame 985 of image 4A_05_101480FA00
(P09_004596_2801_MA_00N107W.IMG and P09_004596_2801_MU_00N107W.IMG).
Data from frame 984 are repeated in frames 985-1322 of those two IMGs.

MROM_0001:

The images acquired in mission phase CRUISE are not of Mars and were
not acquired from orbit (MRO had not yet arrived at Mars), so some
of the values (e.g., orbit number, solar distance) in the index.tab
file are not meaningful.

General:

Some MARCI product names have a latitude and longitude specification
other than the '00N'BBB'W' described in the MARCI EDR SIS.  For
these images, the sub-spacecraft (for off-planet images) or center
(for images of Mars) latitude and longitude were used in the name
either because it was not possible to calculate an equator-crossing
longitude or because such a calculation would have resulted in
duplicate product names.  For example, images on the stray light
calibration orbit 1762 (volume MROM_0013) are named with '27S134W',
'58N146W', and '71N317W'.

The MARCI planning periods are represented in image product
filenames by the mission phase descriptor, as noted in the
MARCI SIS.  The planning periods are:

CRU  Cruise instrument check-out/calibration (August 2005)
MOI  post-Mars Orbit Insertion instrument check-out (March 2006)
T0n  Transition to Primary Mission (September-November 2006)
Pnn  Primary Mission (November 2006 - August 2008)
Bnn  Primary and Extended Mission (September 2008 to present)

where n is a digit from 0 to 9.

MRO's Extended Mission starts on 20 December 2008 and ends on
31 December 2010.  MARCI planning periods for Primary Mission and
beyond, however, are defined by Mars year and Earth month; the
letter represents Mars year, and the number represents Earth
month within that Mars year.

The planning period naming scheme was developed to be consistent
with that of the Mars Global Surveyor (MGS) Mars Orbiter Camera
(MOC) dataset to simplify comparisons of data across several Mars
years.  The solar longitude ('L sub s') range of a given numbered
Earth month is roughly the same across the two datasets; for
example, MGS MOC periods M12, E12, R12, and S12 correspond to
MRO MARCI periods P12 and B12.  The letter B represents beta, the
second Mars year of MARCI imaging.
