a) Average 195 Å intensity as a function of horizontal distance and time for the ROI at 76.6 Mm, white diamonds joined by a solid line give the location(s) of the prominence as identified by Gaussian fitting with error bars shown for every second data point, positions at 11:24 and 18:00 UT are in red bold. b) and c) Inverted intensity profiles as a function of horizontal distance, black diamonds joined by a dotted line show the measured intensities, the blue dashed line is the second order polynomial fit to the background, the red dash-dotted lines are Gaussian peaks indicating the prominence location(s), while the solid black line combines these to give the overall fit.
