The terms of the normal equations are stored in a direct access binary file. The file is organized as
The proneqs file has a record for each normal equation column indicating the record number (heresi record terms) where the column is stored in the Normeqn file
The direct access file is divided into 2 areas. The first area has 1 record for each HERESI record of the normal equations. The normal equations are divided into a number of records determined by an optiminal size determined by the overall size of the normal equations as well as an optiminal record size for processing. There are 4 records for the terms listed above. The second part of the file contains blocks of the actual normal equation terms.
