Codebook for OSIRIS/ASCII Data Dictionary:

The following information gives the layout of the OSIRIS Dictionary as it has been converted by SSDC staff into ASCII. OSIRIS Dictionaries are used to describe OSIRIS Data Files. Note that each record (line) in the Dictionary has 80 characters followed by a line feed character (decimal 10 -- noted as "LF" in the codebook). Note also that the Dictionary consists of a one line "Dictionary Descriptor Record" followed by multiple "Variable Descriptor Records," one line for each variable in the Data File. The Codebook below describes these two kinds of records. The Dictionary can be read with standard statistical software, if desired.
