SuperDARN Radar Software Toolkit (RST) 4.6

Key updates in version 4.6 of the Radar Software Toolkit (RST) include:

• Routine for removing non-gaussian noise/interference from fitacf files (fit_speck_removal)
• Routine to display the contents of old-format dat files (datdump)
• Shepherd (2017) elevation angle algorithm added to FITACF3.0
• Ability to plot multiple fields of view with fov_plot
• Added missing mlt2mlon keyword to MLT_v2 IDL/DLM code
• make_grid detects and concatenates multiple input files automatically (deprecates -c flag)
• Check that the search noise is nonzero before using it to replace the skynoise in FITACF3.0
• Check whether interferometer array is in front or behind main array when calculating elv_low/elv_high in FITACF2.5
• Fixed bugs in plotting libraries, cdf file reading, make_grid and trim_raw
• Update hardware files for DCE and DCN, and PI institution information in radar.dat
• Improved compliance with GPLv3 license requirements
• Documentation updates

The RST is actively developed and maintained by the SuperDARN Data Analysis Working Group (https://superdarn.github.io/dawg/).
