Product File Format
Each product is stored in a separate file in the directory specified by the IRIS_PRODUCT environment variable.
Raw products are stored in a separate directory specified by the IRIS_PRODUCT_RAW environment variable.
Product file names consist of the 15-character site and time to the left of the dot, and a 7-character product type code and machine generated string to the right.
The file consists of the product_hdr structure followed by the data.
The product configuration structure is exactly what is in one of the product configuration files. It specifies how a product should be generated, and so includes some information not strictly required to appear in the final disk file.
