Synoptic maps from mk3 data are available in postscript and binary format. They are available via our anonymous ftp site.
Maps have historically been generated at 1.36 and 1.74 solar radii.
As an experiment, we've generated maps at 1.15 and 1.20 solar radii.
To download the binary maps ftp, click here.
To download the postscript maps at 1.36 and 1.74 solar radii, click here.

The postscript maps should be fairly self explanatory. An X is placed where no data was available. Data gaps of 1 day or less have been interpolated across. The data in these maps are of pBe+10 B/Bsun. The start and end times of data in the postscript maps are given in the map as Bdoy and Edoy.
The maps are in postscript format with the following filenames:
????e.ps ????w.ps
where ???? is the
Carrington Rotation
number, e is east limb, w is west limb,
and ps stands for postscript format.
Binary synoptic maps have been generated from 1991 to present. Map filenames are as follows:
????e1.36 ????w1.36
????e1.74 ????w1.74
where again, ???? is the
Carrington Rotation
number, e is east limb, w is west limb,
and 1.36 or 1.74 is the height in Rsun at which the data
was taken.
The data in these maps are 16-bit integers of pBe+10 B/Bsun. The array size is 360 by 181.
In idl the images would be image=intarr(360,181)
C short image[181,360] Fortran int*2 image[360,181]
The files contain the image followed by a short ascii footer.
On a UNIX system, use the command:
tail -1 filename
or
tail -1 1888e1.74
for example, to see the how long the ascii footer is.
Further information on these data can be found in the file README_BINARY from our anonymous ftp site..
