COVARIANCE DATA FILE FORMAT

 Where covariance files are large, the covariance data may be stored in a separate covariance file. The existance of the file will be indicated in the corresponding EXFOR data set under the information-identifier keyword COVARIANCE, see Appendix B, COVARIANCE.

There are three record types in the covariance file: 

Comment record format	
	Column	1		C
		2	- 9	Data set number (subaccession number)
		10		(blank)
		11	- 80	Comment which includes covariance type and format

Data record format
	Column	1		D
		2	- 9	Data set number (subaccession number)
		10		(blank)
		11	- 80	Data in format given on comment record

End record format
	Column	1		E
		2	- 9	Data set number (subaccession number)
		10	- 80	(blank)
