SOT/NFI filter Disk Center with solar rotation compensation Format 1024 x 512 pixels or 1024 x 1024 pixels Pixel 0.08 arc sec (1x1 - no summing) NaD1 5896 line
I+V and I-V with filter tuning for 9 wavelength positions [-480,-360,-240,-120,0,120,240,360,480]
Time step = 60 s = 2 x 9 shots = 18 shots (I+V and I-V for 9 wavelengths)
This will allow the computation of vertical velocities and magnetic fields at 2 different altitudes using the bisector technique.
test sequence : 5 mn = 5 cycles in order to check the tuning of NaD1 5896 line
full observation : 2 H sequence = 120 cycles of 60 s duration |
