• Speed improvements to map_grd and map_addhmb (~3x)
• New GUI for displaying real-time fit data (fitacfclientgui binary)
• Updates to the data simulator (sim_real and make_sim)
• New command line options in field_plot to correctly display the radar field of view
• Improved color control in plotting routines
• Updated documentation

RST 4.7

Key updates in version 4.7 of the Radar Software Toolkit (RST) include:

• New routine to list the transmission frequency bands present in a fitacf file (find_freqband)
• New functionality and documentation for the data simulator (make_sim)
• Updated C and IDL code for reading the new hardware file format (Note: the old hardware file format is incompatible with RST 4.7. The new hardware files are included in this release)
• Bug fixes that affected compilation on some systems
• Bug fixes in various analysis and plotting routines
