Notes. The following quantities are listed in the next six columns: temperatures, velocities vmt of microturbulence, optical thickness τ0(Hα), ionisation degrees i of hydrogen obtained from GBO in Hα and Ca ii H, and values of ionisation degrees j1, j2 of helium estimated from comparing of the 193 Å and 335 Å based masses. For each prominence observation (except for the small prominence No. 2), intervals within which values of T, vmt, τ0(Hα), i vary in the prominence areas are listed. In rows under intervals, numbers preceded by the abbreviation “mean” are values averaged from whole prominence areas.
The small prominence was visible only in AIA and X-ray XRT images, it was not seen in Hα slit-jaw image of the SLS spectrograph. Therefore, no times are shown for the SLS observations, just the date. Unique value of i for the whole prominence was estimated together with j1 and j2 by comparing the 193 Å and 335 Å based masses.
