Using FLCT to Obtain Spectral Information From MOSES Data
Abstract
The Multi-Order Solar EUV Spectrograph (MOSES) is a high cadence slitless spectrograph that images in He II 304Å. The large field of view (20’x10’) combined with the ability to quickly obtain images containing both spectral and spatial information makes MOSES an ideal platform for probing small scale, short duration flows resulting from magnetic reconnection in the solar transition region. The ease of obtaining co-temporal spectral and spatial data with a slitless spectrograph is counterbalanced by increased difficulty required to disentangling the information captured in the images. The Fourier Local Correlation Tracking (FLCT) routine developed by Fischer and Welch (2007) is developed as a technique for obtaining Doppler shifts and line widths from small scale flows imaged by MOSES. Results are reported utilizing this technique on simulated images and MOSES data.
