SSO Meta-Data File (December 3, 2009) [sso05 WSDC D-I149, vsn 1.2] Interface Name: SSO Meta-Data Type of Interface: table file Written By: SSOID (ssoid)____________________________ J. Fowler Read By: DBPREP___________________________________ T. Evans QA_______________________________________ H. Brandenburg QA_______________________________________ D. Kirkpatrick DESCRIPTION: The SSOID Meta-Data File is written once per execution by the SSOID module ssoid if the command-line specification with the flag "-om" is given. It contains a summary of control parameter values and statistical information about the number and characteristics of SSO predictions and WISE sources. The format is that of a WISE meta-data table file, i.e., functionally it is somewhat like a table file on it's side with a single record per variable. Each variable is provided with a description as part of the entry.
