About SDDI

Solar Dynamics Doppler Imager(SDDI) was installed on SMART in the end of 2016-Apr to observe the motion of filaments eruptions.
In contrast to the previous observing system, which was able to observe the velocity of filament eruptions up to 60km/sec, the new system can capture the velocity up to 400km/sec.

The wavelength designated on the data is not exact because of the slight variation of the central wavelength of the Lyot filter due to the temperature excursion.
To deduce the exact line-of-sight velocity, a calibration of the wavelength is necessary by referring to spatial average of the solar disk. If you conduct a quantitative analysis using the SDDI data, please contact us.
