The CDF files produced by this tool comply with the International Solar- Terrestrial Physics (ISTP) Key Parameter Generation Software (KPGS) Standards and Guidelines (12/92). makeCDF is written in standard ANSI-C, and has been tested on VAX/VMS, Sun/Unix, and IBMPC/DOS platforms. It is distributed freely by the NASA/GSFC/Space Physics Data Facility. It contains no proprietary software. makeCDF is still under development. Planned enhancements include increased validation of user input, performance optimization, expanded on-line help, and additional Epoch calculation algorithms. Any additional functional enhancements requested by our user community will also be added, as time and resources permit. makeSFDU is a portable tool that can generate a minimal detached Standard Formatted Data Unit (SFDU) from a CDF file which complies with the International Solar-Terrestrial Physics (ISTP) Key Parameter Generation Software (KPGS) Standard and Conventions (12/92).
