Sagan Open Stratigraphy file:

Sagan allows users to read, display, and depth-shift up to
five different types of biostratigraphic (foraminifera,
nannofossils, diatoms, radiolaria) and  paleomagnetic
(reversal) age control data. The files are in a standard 
tab-delimited format which can be exported from spreadsheet
programs such as  Excel (see "Stratigraphy Data --> Input"
Help pages).      

The user specifies the files to be read using "OPEN... -->
STRATIGRAPHY FILE" under the FILE menu. Once located, the
user identifies which type of  stratigraphic data the file
represents - this color-codes each of the five stratigraphic
data types. When read, the data are plotted as range bars to
the  left of the core data. The user may click on the symbol
of the stratigraphic  label next to the range bar and the
information about that datum will appear in the dialog box
at the bottom of the main window. 

--------STRATIGRAPHY DATA FORMAT----------
The files can be developed on simple spreadsheet programs (such as Excel or 
Kaleidograph) and then exported as tab-delimited files and then transfer to 
the Sun workarea. 

File format (Tab-delimited(or white space), all on one line):

Where:
Datum_name: Up to 30 character-long string of the datum identifier. NOTE:
  There must be no spaces in this field, please use an underbar "_" or a 
  Hyphen "-" instead of spaces, otherwise the file will not load properly.

Label: The user-defined abbreviation for the Datum_name which is suitably 
  short for text display adjacent to the core data in the Composite and 
  Splice panels of the main Splicer window.  
  
TopAge: Upper age limit (in Kyr or Myr) for the datum. If upper=lower, enter
  the same value in both fields.
  
BotAge: Lower age limit (in Kyr or Myr) for the datum. If upper=lower, enter
  the same value in both fields.

Int1: section depth(cm)
