This directory (/mk3/map/old) contains Mark-III coronal 
east & west limb synoptic data contour maps in POSTSCRIPT format.
They contain scaled polarization values and are for viewing 
purposes only. NOTE: These are generated with an old calibration and will be
recreated over the coming months. Check the /mk3/map/ps directory for the new
versions.

If you are unable to handle this format, or if you are interested in
obtaining maps in binary format that contain the calibrated polarization brightness
values, or if you have any questions/suggestions please contact:

FILE DESCRIPTIONS:

histxxxx.aei   
histxxxx.bei
histxxxx.aem
histxxxx.bem

All hist* filenames contain four digits representing the number of the Carrington
rotation. Each file contains half a rotation at one limb. Files ending in .aei
containing the first half of the rotation at the east limb and .bei contains
the second half of the east limb rotation. A file ending in .awi is the
corresponding west limb map.
The 'i' at the end of a file indicates a coronal height of 1.36 solar radii 
(inner corona) and the 'm' at the end of a file indicates a coronal height 
of 1.76 solar radii (middle corona). 

Files beginning with 'sh' are the same data mapped onto a sphere. Filenames have
the format: shDOY-YR.ei where DOY is the day of year at the east limb, and YR is the
year. All spherical maps are at a height of 1.36 solar radii (as indicated by the
'i' for inner corona).
