Same as Fig. 6, but for the positions two spatial pixels below (south of) and above (north of) the pixels where the line profile parameters in Fig. 6 are taken. This essentially follows the southern and northern edges of the loop. The variation along the southern edge of the loop is denoted by asterisks, and the variation along the northern edge by crosses. The diamonds show the variation along the central loop axis (cf. dotted line in Fig. 1b) and are identical to the data shown in Fig. 6.
