Walt AkersJune 01, 2022Initial version of Geometry Matrix software is release. This version supports only one matrix at a time.- Walt AkersJuly 13, 2022Version 2 of the Geometry Matrix software is under development. This version has a "Matrix" field at the beginning of each info column that identifies which matrix it is associated with. A field with no matrix name applies to all matrices. The matrix itself remains unchanged.
- Yulia FurletovaJuly 20, 2022This is a prototype release for the Far Forward/Far Backward Interaction Region and is being used to test the configuration of the system. The data in this release is for illustration purposes only and will be removed when a verified release is produced. The reader should not rely on the information provided in this release.
- Yulia FurletovaJanuary 19, 2024Expanded release of the Far Forward/Far Backward Interaction Region. This is an interim release that will be updated with additional data as soon as it becomes available.
