Study 000342: ACRONYM: dei_qs_80_slot40_low Takes two neighbouring slot positions, separated by 38". The aim is to put the left and right window edges repetitively at the same position on the Sun, so that both wings of high Doppler shift events at the window edge appear beyond the main line window. A small sample of clean slot windows have been chosen. Windows are wide, not less than 64 pixels TARGET: Quiet Region of Sun EXPOSURE TIME: 60 s SLIT: 40" FOV: 78"x384" SPECTRAL WIND: 6 DATA COMP.: JPEG(Q=90) Duration: 2m 32s Volume: 1.3 Mbits Target: Filaments, Prominences, Quiet Sun.
