The uploaded data file should be in the plain text format with the variables, r, v_cme and v_sw stored in the three columns separated with space. Below is an example:

      30.3809      705.704      425.158
      31.1708      704.666      426.046
      31.9812      703.607      426.918
      32.8127      702.525      427.772
      33.6659      701.421      428.606
      34.5412      700.295      429.425
      35.4392      699.145      430.224
      36.3607      697.971      431.006

Note: r must be in units of solar radius, and v_cme and v_sw must be in units of km/s.
