The effect of image vibration on the determination of radial velocities of spicules on the solar disk.
Abstract
Given optical parameters of spicules ΔλD = 0.20 Å, τ0 = 1, Δλ2 = 0.44 Å their absorption profiles on the disk were calculated taking into account the image oscillation with δ = 0arcsec.5, 1arcsec.0 and 1arcsec.5 in order to find out if the absorption center shifts. It turned out that the image oscillation practically doesn't influence the shift of spicule absorption (Δλr). This suggests that radial velocities of spicules on the disk are really small.
