Kinematics of the erupting filament and associated SXR flare evolution. (a) Height estimations of the filament (black markers). The error bar presents the five-pixel shift in finding the matching point along the epipolar line. The corresponding black solid line indicates the smoothed height-time profile. (b) Speed and (c) acceleration of the filament obtained by numerical differentiation of height-time data (dots) and smoothed profiles (lines). The shaded areas give the error ranges. (d) GOES 1−8 Å SXR light curve (black curve, left Y-axis) and the corresponding change rate (gray curve, right Y-axis). (e) STIX count rates at 4−10 keV (red), 15−25 keV (blue), and 25−50 keV (dark blue) energies. The vertical dashed lines mark the peaks in the 25−50 keV STIX curve (dark blue), the GOES SXR flux (black), and its derivative (gray).
