Solar Flares and Active Regions
Reconstructing the 3D Reality

The Siberian spectropolarimeter (2-24 GHz) dynamic spectra are stored as the IDL SAV files. Each SAV file contains the following variables:

  • DATAF: 1D 16-element array of the emission frequencies [Hz].
  • DATAT: 1D N-element array of the recording times [seconds after 01 January 1979, compatible with the SSW anytim conventions]; N is a variable number of times.
  • DATAL: 2D N×16-element array of the left-polarized signal intensities corresponding to the above specified frequencies and times.
  • DATAR: 2D N×16-element array of the right-polarized signal intensities corresponding to the above specified frequencies and times.

Note that the data are partially calibrated, i.e., the fluxes are in arbitrary units (not sfu); background is not subtracted. In the supplied images, bad data in some frequency channels can be omitted (the corresponding areas are shown as black); the SAV files contain data at all frequencies.

The supplied data can be used for qualitative and semi-quantitative analysis (e.g., studying the delays between X-ray and microwave bursts, searching for fine structures, etc.) only.
