MROX_0162:

CTX was powered off at approximately 13:49 on 2007-07-20, during
transfer of data from image P09_004596_1832_XN_03N108W.IMG
from the instrument to the raw SSR.  Data between lines 4151 and
4357 are repeated in lines 4358-52224 of that IMG.

MROX_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.

CRU_000013_9999_XN_99N999W.IMG was created manually from a source
file 4A_04_0001001000_G_01.DAT which contained data gaps.

General:

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

CRU  Cruise instrument check-out/calibration (August-December 2005)
MOI  post-Mars Orbit Insertion instrument check-out (March 2006)
T01  Transition to Primary Mission (September-October 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.  CTX 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 CTX periods P12 and B12.  The letter B represents beta, the
second Mars year of CTX imaging.
