|Slow-sound||127 ± 13||9.7 ± 0.4||8.0 ± 2.0||–||–||436 ± 47||416 ± 52||–||–|

Notes. The loop length L, the period P, the temperature T, the densities ne and n0 are estimated from the observations and are used as input values for the determination of the sound and Alfvén speeds. The magnetic field is estimated via coronal seismology. In the slow-tube wave approximation, the inner density n0 of the hot loop is found from the Alfvén speed and the value of magnetic field, which has been previously inferred from the kink wave.
