        CLIC\VARIABLES POSITION ON|OFF

    Source related information (Scan based).

      SOURCE           Source name
      LAMBDA           Source longitude-like coordinate (radians)
      BETA             Source latitude-like coordinate (radians)
      OFF_LAMBDA       Offset in lambda (radians)
      OFF_BETA         Offset in beta (radians)
      EPOCH            Epoch of coordinates (if equatorial)
      PROJECTION       Projection used for offsets
      FOCUS            Focus position used
      FLUX             Source flux (Jy) for calibrators
      SPIDX            Source spectral index for calibrators
      STOKES_I         Reference Stokes I (Jy)
      STOKES_Q         Reference Stokes Q (Jy)
      STOKES_U         Reference Stokes U (Jy)
      STOKES_V         Reference Stokes V (Jy)
      STOKES_SPIDX      Model vector: alpha(I), alpha(p), RM [rad/m**2], al-
    pha(V)

    The reference frequency is R_FLO1 + R_ISB*R_FIF1 (MHz). See  SET  STOKES
    and  STORE POLMODEL for model evaluation and storage. The V spectral in-
    dex is stored but not currently applied.
