Notes.

^(a)

Slope of log DEM with log T [K] in the lower transition region (4.6 < log T [K] < 5.2) based on SPICE data.

^(b)

The same in the upper transition region (5.2 < log T [K] < 6.0).

^(c)

EM-weighted temperature in the range of 5.9 < log T [K] < 6.5 based on AIA data.

^(d)

Magnetic process exhibited by the footpoints prior to the SPICE observation (E is the emergence, C is the cancellation, and R is the random motions; Sect. 3.2.3).

^(e)

Quiet-Sun measurement for comparison.
