SuperDARN Data Analysis Working Group

Basic information

    Working Group Charter 
    Procedure for implementing major changes to the software 

SuperDARN software maintained by the WG

Zipped (for installation istructions refer to the respective file)
    Radar Software Tookit 4.0 (RST4.0)
Github repositories
    FITACF 3.0
!!! Please note that RST4.0, as a reference/transition package, still uses as default the "old" style FITACF2.5 (as well as old AACGM, old gridding, old statistical model etc.), 

while FITACF3.0 can be installed as a separate package (it still requires RST for reading/writing and hardware information).

Tasks (in historical order)

    Task #1: missing DOF term
    Task #2: "bad phase" flag
    Task #3: cumulative CRI level
    Task #4: misreading AACGM coefficients (from AJ)
    Task #5: Dealing with zero values of smsep and txpl (from KS)
    Major task: Optimisation of fitting routines (five out of 6 propsed modifications have been implemented in FITACF3.0)
Right now all development is documented in the respective github repositories above.
