MARINER 10 IMAGES -- ISIS FORMAT
The ISIS format files
contain raw Mariner 10 image data.
The labels HAVE updated camera pointing and spacecraft position as reported in
Robinson et al., 1999 and here .
These position/pointing data can be found in a seperate
text file
0.2442136162981461D+07 00027090 JULIAN_DATE&FDS
-0.1769587929046400D+06 0.8521772271460000D+04 -0.5286737746724800D+05 SXSYSZ

The first line contains the Julian Date at which the image was acquired and
the FDS clock count number (which is also the image file name).
NOTE that the onboard clock reset to 0 several times during the
mission so the times can get confusing. This feature of the mission
is well described in the Murray and Burgess
Book. The second line contains the spacecraft position coordinates.
The third line contains the camera pointing angles.
Additionally, it was found that many of the ancillary data found on
the raw EDRs were incorrect (Filter position, exposure times, etc), these have been fixed
by examining published data and self consistency checks on the data. So be cautioned that
errors may remain! Also the labels of the files contain reseaux positions determined by
autocorrelation (ISIS module FINDRX) and later updates through manual inspection.
The same reseaux positions are also available in text form (ascii files).
CAUTION: This is a large subset of the full Mariner 10 dataset: all these images were included in
the control network effort cited above. Some of the original Mariner 10 images
were not found in digital format. An effort is being made to recover these from raw
telemetry tapes. Also many of the low resolution approach and departure images were not
controlled. An effort is underway to manually control images orphaned from the global
control network.
